This can be your workhorse driver. Compared to a destroyer or force. The ultrium tends to be a little less overstable than the premium, but far from flippy. 

I'm going to go with 5 stars even though I'm not sure the flight numbers are quite accurate.  I have this in the Ultrium plastic, which makes for a fantastically grippy and comfortable mold.  I like to throw this disc primarily flat or on a slight anhyzer to take advantage of what I feel is some exceptional glide.  For me this disc follows a very straight line for a little over half of it's flight, having a just a little left to right turn before gradually falling into its fade.  I'm not sure I'd list this as a 3 fade... maybe a two, but the fade is very dependable.  I seem to reach for this disc when I want to keep my shot relatively low, not lose distance, and rely on it's dependable fade.  For me, this disc is very comfortable in the hand and the Ultrium plastic has really held up well.  

There you are in the Disc Golf store, or poking around Infinite or your favorite disc golf site looking to try out a new distance driver.  Hmm, what do I want to throw.  You've tried Destroyers but gosh darnit all the good ones are getting scarce and the new McBeth's won't work for your arm.  Then you start running through the options...DD2, DDX, Nuke.  don't feel quite right...and you cannot get the distance out of a PD2 or Defender, Enforcer.  Maybe you'll try understable big flex lines...Whoops all your Shrykes and Thrashers go right....right...will it come back..Nope.  Hmm, you're stumped. Looks like it's time to think outside the box.  Your first and possibly last stop should be the Razeri in Ultrium.  (Premium is too beefy for most 300-350 throwers. maybe 400+ folks)  

First thing.  I've throw 2 of these in Ultrium.  One flew like a longer Trespass which is exactly what I want.  My current one is a bit more stable but I think that is down to the sharpness of the wing that wasn't beat in as my old one was a little used.  

The Razeri has plenty of glide (like a nice domey D1)  I would also say there is a little turn with a good snap on the disc.  Prodiscus says 3 for the fade and I just don't see it.  I see a much less pronounced fade which I prefer.  

As with the entire lineup the plastic feels great.  Prodiscus Ultrium and Kastaplast K1 are the best feeling plastics on the market.  Sure they come from smaller manufacturers but they are the best.  Ultrium is extremely durable.  Multiple seasons to fully break in and because too flippy.  

My 175g Razeri is very overstable but it's actual glide is noticeable even through it's extreme fade. I'd compare Razeri's feel in hand to Prodigy's X-1 and Latitude 64's Scythe(Razeri has nearly the exact same dimensions as the Scythe). I can't wait to further beat my Razeri in and see it's flight stretch in distance. After trying Prodiscus's putters(Sparta and Jokeri, which both made my bag) in all three of their plastics, I'm convinced Prodiscus has the best plastics on the market and will be buying more from them in time. Razeri is for power arms and will be a champion for overhand throwers as well as for strong backhand and forehand throwers.
