I had a predator Ikon, but didn't like the sticky faux leather wrap. I wanted to just try a wrapless cue, and switched to a black wrapless p3 and settled in right away. It's a bit thicker than a normal butt, but I got used to it and even prefer it now.
Since I already had two z2 shafts, I just needed the p3 butt and Nielsen billiards in Illinois gave me a good deal and shipped it over right away.
The only p3 downside is the weight system needs a special tool to get the threaded weights out to adjust. But all new predators have that weight system now. That kit costs sixty bucks. Other than that it serves it's purpous well.
Also like another poster stated, the hit is a little empty in regards to the z2. I eventually went with Longoni s2 shaft made with a uni loc joint, and it was just the feel I was looking for.
