I haven't really thrown mine enough to provide a complete review, but I can share my experiences with the Maxxx.
I drilled mine with the pin 5" from PAP, above the fingers, with no XH, and I left it in box finish. I've used it on a fresh league shot with a decent amount of friction, in a second-shift league on Pro Anvils, and in the first block of a tournament with a house-type condition. What I've seen so far is that the Maxxx is so strong off of the friction that it lets me get quite a bit further into the oil, and yet it doesn't quit at the turn when I give it room. Despite the box finish, the Maxxx doesn't labor for me in the front part of the lane. Perhaps as a consequence of this, I *do* have to get the ball to the friction, otherwise it'll want to push too far through the volume.
I'm looking forward to trying the Maxxx on a flatter high-volume pattern where I can play a more direct line to the pocket.
Hope this helps.
