In Phoenix line this disc feels completely different. Its not gummy like other phoenix line discs and it has a super dome to it. It feels like it wants to be overstable but its a straight flying disc that pops up to flat but doesn't turn over. The plastic makes it feel pretty strange which is why I gave it a 3 star.

Got this disc out of the first three pack of discs I purchased (putter, mid, driver) all with the kestrel stamp. After playing a little over two years now this disc and the Yao (mid) are both still in my bag and I throw them regularly. I've gotten better with my form and can throw a putter decently (about 300 ft) so typically throw putters more than midranges now. The Gui is my go-to driving putter and approach disc. After two and a half years of being in my bag and being thrown multiple times per round this disc is still in great shape. It will hold a hyzer line and when thrown flat will have a consistent fade. Haven't quite aced with it yet but on four (freakin' four) different occasions I've hit metal off the tee with this disc. Highly recommend if you want a stable driving putter. 

I spent 2 months in China and I was missing Disc Golf so bad that I found a place to buy some discs, which was not easy, and found a place to throw them, which was also not easy.

I happened to find one of these putters and after holding it I knew immediately that I had to have it. This is a fantastic power driving putter. It does not flip at all. It stays very true under high power drives and can easily reach 300ft for high end players. This disc does not flex line under power, I cannot stress that enough, it flies straight with a very gentle fade at the end of it's flight if you throw it high enough. If you throw it straight, it will tend to land straight.

The Phoenix line plastic is more durable than Innova's Champion or Discmania's C-Line. Hard to believe? Believe it. I've smashed mine into a road and a friend of mine has a Da'E in Phoenix line and he's hit roads, rocks, trees for over a year now and the worst it has is scuffing on the surface. 

For beginners I think this disc would be great for learning to throw straight putter shots off the tee. I cannot recommend it enough.
