The JK 2022 tour disc has become one of the most used discs in my bag.  It is fantastic for both forehand and backhand.  It is straighter than other runs I have thrown - pushes straight father before it's reliable fade.  Despite it being relatively flat, it has good glide and can get some solid distance.  The flat profile makes it very comfortable.  The swirly star plastic looks great and feels great in the hand.  Will for sure be picking up several back ups!  Highly recommend. 

Awesome disc, favorite Innova plastic type. The Koling Thunderbird is maybe a bit more overstable than a regular Thunderbird. Love it for big right to left shots thrown rhbh.

Swirly Star "Big Jerm" Thunderbird (175g) - I bought this disc for no other reason than to support Big Sexy commentary. I thought I would try it out and at first I didn't really like it that much. I couldn't throw it forehand very consistently and my arm-speed wasn't great. But I kept it and took it out of the spare bin recently and to my surprise it became a very complimentary disc for my Star Valkyrie. The Valk flies super straight with just a little turn. The Thunderbird will also flip up to flat and stay there for a long time with a nice forward finishing fade to the left (RHBH). It is what I had hoped the Teebird would be to my Leopard. I definitely recommend the Thunderbird if you like the Valk and want a little more stability. 

This Thunderbird is great for wooded courses! I love this disc for straight tunnel shots that need a finish to the left. You can put as much on this disc as you want to and it will not turnover. It beats in very nicely as well as through time mine has become a bit straighter while still having the overstable flight that a Thunderbird carries. Definitely would not recommend for beginners because this disc takes a lot of arm speed to throw but for advanced players, its a must have in the bag.

175 Big Jerm Swirl Star

This disc flies exactly as the numbers say.  If anything it might be a little bit faster than the numbers. When thrown flat it has a straight high speed flight with a predictable fade. However, not the meat-hook fade of a Destroyer, PD2, Enforcer, or any other Max distance overstable driver, yet there is not much of an overall distance difference, despite the Thunderbird rated as a slower speed.

This is a go to disc for me. It fits use for a variety of different shots it will hold anhyzers, both forehand and backhand, and flatten out just enough to continue working but not turn into a throwller. When thrown flat it does not turn over much and will fade consistently as the spin slows. I can count on this disc to be very consistent. In swirly star it looks great and is very durable. 

This is such a great disc to have in your bag for certain situations. Thunderbirds are very stable discs until they get beat in a bit and are somewhat hard to turn and burn. This disc REALLY shines on headwind and crosswind drives as it will not turn and burn and will get you max distance. I own a Swirly Star and GStar version and I can say they fly very similar. My preference is GStar for this mold because it is a bit flatter and I prefer less domey discs. It flies true to its numbers and will always have a spot in my bag.

I got a 175g Star Thunderbird for a stable driver. I have got a decent arm and this disc can hang with my distance drivers! I throw this disc RHBH about 400-420 average. When thrown flat this disc will produce straight flight with little fade. It will correct itself to flat if thrown with a slight hyzer. If thrown on a slight anhyzer with a little height it will flex out for a nice s curve. If you don't have a big arm try a lighter version of this disc. If I need distance with a little fade Its the Thunderbird everytime! I would rate the numbers true to the stamp. Bigger arms will turn this over a bit once it starts to beat in.

This is a very stable Thunderbird.  It's not quite Sexton Firebird stable but 1 step down in stability.  Big arms & side arms will love this disc!  This disc starts to hyzer pretty early for me, I think it will make the bag as my stable hzyer disc, especially once I beat it in a bit.

Just recently bought this disc. Only played 3 rounds with it so far and I haven't necessarily gone out of my way to throw. I only throw it when I feel appropriate. With that being said, throwing this RHFH is a breeze. It flies so straight for a good 300ft before fading out exactly how you'd expect. But it took me a couple flicks to get the right speed. I turned it over the first 2 or 3 flicks unintentionally. Once I got the hang of the speed it flies like a dream. My only critique isn't really at fault with the disc itself but every time I throw it RHBH I have trouble with the grip. Of the 6 or 7 times I've thrown it BH I've either grip locked it or it's slipped out of my hand every throw except for one time. And that one throw it flew dead straight for about 300-350ft and basically laid down as it started to fade. Once I figure out how to release this disc I think I will use it often. Highly recommended for straight shots in the 300-350ft range.

Swirly Star Big Jerm Tour Series 175. I throw almost all Trilogy and bought this disc to support Big Jerm. The more that I have played the more I want to mimic and throw discs like the top pros for field days and just to try out. I have bought a PD2, Destroyer and now this thunderbird. I like it a lot, do not know if it will make my bag, but a great fairway for straight to hyzer shots, and good for shorter tunnels needing to end left. I see why almost every Innova players throws one along with Teebird3's.
