I had a friend who bought one. (The original all-black version) He finally sold it and his other Predator cues and shafts and bought a custom cue from Kerry Zieler with "regular" shafts. He plays better IMHO with the Zyler cue and prefers the feel, but neither of us are Pro-level players so that is a very relative statement.
I tried his P2 for a while before he sold it and to me it felt just like most other cues with Preadator shafts I've hit with. I don't like the hollow feel of the Predator shaft so it was not attractive to me. If you like a Predator shaft then it's a question of if you like the design and price of the P2 cues. To me they seem very expensive for what they are, although I admit I prefer the P2 design over most of the other fancy cues Predator sell under their brand name.
Personally I wanted to move to using Predator technology I would have a shaft blank fitted to a butt made by a good custom cue maker.
