The Xero used to be the P1x and is still amazing. These will always be my turnover to straight driving/layup putters.This is my cheat disc along with a Fuse since my forehand isn't great.  I have 4 aces with the Xero so I highly recommend picking one up. They do have a bead which most people don't like but I love being a wizard putter. The problem with these are the plastics. XT is solid but DX and R-Pro get chewed up quickly losing stabilty. I just got a Glow Apple XT and its by far the worse plastic. I maybe threw it 15 times and is beat up. Hope Innova comes out with a Champ Version of the Xero but that could be asking for a lot. Pick one up today!!

Exceptionally straight putter, great for long straight bids and floaty anhyzers. The disc also keeps you honest by reflecting any issues with your throw in it's flight. Great disc for beginners to iron out their form with

This disc is great for learning how to throw. It flies super straight when thrown well. But if you throw it poorly, it won't correct for your mistakes. It has helped a lot with my short game inside 200 feet. 

I bought this disc mainly for long, straight putts and have not been disappointed.  I am able to putt from the edge of circle 2 and it stays on the line where I release it with a little power.
