I did not have much luck with this disc. I found it to be pretty stable and did not have the -1 turn I was looking for. I switched to a Valkryie and found the extra distance without compromising on consistency, which was the slot I was trying to fill with the driver. Probably a fine disc, just not for me. 

One of the best 9/4/-1/2 drivers in the market. I really respect the 9/5/-1/2 slot in the bag. It's what I consider a workhorse disc on most courses for above average arms. I will say, mine had some sharp edging flashing so I smoothed it out on a picnic table. Other than that you can't complain, it's an amazing Control driver. 

Noticed it was more understable out of the box around -1.5, 1.5 for turn and fade, respectively. Once it broke in it became a perfect hyzer flip over but had enough fade to fight back into a nice clean finish. I enjoyed this disc a lot until it just broke in too far and became a roller even at 60% power RHBH.

Great work horse disc. Can be put on most lines and fades out perfectly everytime. Very predictable flight which makes it such a great disc. Great for all levels of play. Obviously more advanced players will get what this disc does and can perform those shots without any difficulty. Newer arms will still be able to throw this disc fine perhaps not with the distance needed, but will still really like it. Released on a flat line it will make a beautiful s flight and land where you want it to.

This is my primary driver, as everything fit perfectly for me. For how flat the disc is, the glide feels insanely forgiving. The rim feels smaller than a few other 9 speeds that I have, which is easy to hold even with bigger hands. I don't think -1 is wrong for the turn, but it is a very easy to achieve turn without having to put everything behind it.

I bought this disc after I had started to develop consistency in my form.  I love it from the first throw.  It's forgiving and also shapeable.  My big Z has a very reliable east fade when thrown flat or hyper flipped. 

Great disc! I like it on the tighter fairways where I want to either throw it straight for 200'-300' to fade into a specific spot for an up shot or release it straight with more power and it tends to go straight for 150' or so and slowly turn for another 150' or so for a nice finish. Like with most discs, don't put too much air under it in the woods because it will hyzer out early. Great, tough plastic and it feels good in the hand.

This disc has become a go to in my bag. This thing goes further than some of my distance drivers. It is lazer straight and has a reliable fade. 

I put this mold in my bag well over a year ago and I still have a 165 ESP from when I first started with this mold.  For the most part I compare this to Dynamic Discs Escape, but it's more dependable.  I threw escapes for a while and any headwind could send this thing from Texas to Florida on a RHBH.  When McBeth first mentioned the undertaker (I know it was out before he joined Discraft), I gave it a try.  Now, I carry 3-4 depending on the course (I have a 2 level zuca cart, so I have room).  For the titanium, I can throw this on a slight turnover with full power get some turn and then see it come back every time.  I consider this the perfect stability for dependable 300 foot throws.  The Big Z is a touch less stable, but still keeps it in the fairway.  The ESP can beat in to a great hyzer flip or even a great turn over thrown flat.  I also have a Z version that is more stable compared to titanium.  Then a Z sparkle ledgestone one from last year, this is a completely different disc.  I took out my felon recently because this thing is so stable.  So, I would say over all the numbers are correct for big z, esp, and titanium if new.  Once used, the ESP gets a -2 turn and a 1 fade.  The Z sparkle I would give 0 turn and 3 fade.  If you are looking for a mold that will give you control w/ distance and escapes or other similar molds aren't reliable, pick up one of these.  

Very overstable, didn´t see any turn with my 300+ feet of power, maybe I just can´t get it up to speed. Comfortable rim and the plastics are nice.

This is for the ESP plastic Undertaker. I have been looking for a disc to fit in the slot between my Teebird and my Thunderbird and today I was given this disc by a friend. I was wanting something that faded a little more than my dead straight Teebird, but not as much as the thunderbird and I feel this disc was everything I was looking for. With a slight hyzer it will flip to flat with a consistent fade at the end or can be thrown flat to turnover and still finish back slightly to the left(RHBH).

Still gotta test it out a bit more but it seems to fly pretty well into the wind with slightly more hyzer to get the same results!

Good for players who are a couple months in that have developed enough arm speed to keep this disc from just hyzering out.

The Undertaker is one of my favorite controllable fairway drivers. I love this disc for straight shots around 300-350 feet, I feel I can trust it on a slight hyzer to flip up and ride straight for a while. It can turn over on flat releases with higher arm speeds with a beat in disc. Big Z is my favorite plastic for my arm speed, Ti seems slightly less stable and ESP in my experience is the most stable. 

This is my favourite control driver on most tight holes, especially any hole with OB right (RHBH). With my beginner-intermediate arm, I can throw this with quite a bit of power, and trust that it will hold a fairly straight flight and fade somewhat hard at the end. In the Z line, it handles the wind well and seems fairly overstable. I also like the feel of this disc, both forehand and backhand. Definitely recommend!

Favorite disc I've ever owned, beat in and then goes dead straight with somm fade at the end. Love it for backhand and forehand both.

Udertaker ir stable enogh to manage many shots that are slightly overstable. You can flip it to flat and even little over, but it wont go over. What is does is that it goes far for its speed. I can get distancewise same thing with some discs with speeds of 10&11and this one. Really love the solid performance and keeping it straight and reliable fade (and minor overstability).

I am not using it for many kinds of shots but when i see 300 feets and fade left in the end, this is a reliable option for that righthand rackhand shot. In any kind of wind conditions it can manage THAT shot. I havent used it for many other shots, but it can also works mirrored to forehand shots if you need it... it will just fly little more understable when thrown with forehand and pan out more...

Distance and accuracy are strong with this one.

Being  a senior with mediocre arm speed, I can only use this disc for downhill tee shots.  Thrown flat, it has a bit more turn than I expected, but the glide is phenomenal.  I first owned a macro-sized Undertaker and could fire that thing dead straight with a nice soft fade;  I get an S-curve out of the real deal.  I bought it at 167g and use it on windier days (for me that's a heavy disc).  Most of my distance drivers are in the 135g range.  Added bonus is that the Big Z logo is pretty cool.

Talk about a straight disc. This thing has a slight fade at the end and is very reliable. It is great for holding lines with just a little ability to come back at the right moment. The best fairway i think i have thrown yet. a must have in the bag

Basically an Orc, but marginally slower, and with a lesser rim width. Healthily overstable, but not a meathook, and does in fact show some turn. Forehands surprisingly well for a somewhat domey disc. Don't let the name fool you; this disc is not understable.

I love this disc! I have been throwing this disc with flat for around 350 with about 80 percent power for a consistent tight s. The disc will turn slowly, stand up, then fade slowly the last 50 feet. I bought one and after some field work with it I came home and ordered 2 more.

To those who read the below reviewer, the Firebird and Valk both have deeper rims than the Undertaker. I think they probably were talking about the height being cumbersome to their particular style of forehand, in which case poptop Firebirds and Valks would pose the same issues. 

Anyway, this disc is a taller driver that gives it great glide despite it's healthy LSS. I still preferred the even taller ESP Tracker (hence the loss of a star), otherwise depending on the length of the course this is my perfect go to. X plastic, which just came out, for the turnovers (anny release for now, till they beat in), Big Z and Z for the tight S curves and straight to fade shots. Great disc, that can handle power. It's like a Thunderbird, with less flip, and a smooth straight wing with no concavity (which is my preference).

I'm a first year player for my first ace with this disc. I hit a straight hole at 229 feet with a nice fade shot rhb . This disc does what I tell it to, unlike my ex. When I need a long flick approach this disc drops on a dime for me. Most say it doesn't fight wind well but my Undertaker's cut like a knife. I have five of these at diff weights and I have a love for each of my un dead discs.

The Undetaker is a new addition to my bag, and so far I am really enjoying it! For one, the Big Z feels super nice, and from a company with a lot of cringe worthy stamps, the Undertaker isn't an "insta-wipe and dye" disc. 

Vanity aside, this disc flies real nice for me. It has just a touch of turn with a consistent fade that can fight through a headwind. For an overstable disc like this, it glides very well. It is a nice flight path to watch.

I throw a Discraft heavy bag and this is one of the better discs they've come up with recently. The Heat, Mantis (if they stuck with the prototype version it would be a different story), and Roach were all solid releases but nothing that I would really say were going to become staples of serious players bags. The Undertaker however I think is going to be a disc that is going to be a mainstay in many, many bags for years. 

I am withholding the 5th star until I see how it beats in.

UPDATE:

I am giving it the 5th star. It has beaten in to have more turn at high speeds, but holy moly can I get a gorgeous hyzer flip out of it now. Lazer straight with a moderate fade at the end. Thrown flat it certainly turns a bit more and doesn't always fight back to center, but if I want that straight shot I can flip it consistently. Boom!
