Suh--
I have the original Marauder-- drilled pin above my fingers (positioned in the middle of both) with cg in the middle of my palm (about 3.5" pin to cg in length).
I've played with the surface of the ball quite a bit; from 500 the whole way to 4k without polish, then back to different grits with polish. Finally, I decided to add a balance hole to tweak the reaction just a touch (put the hole on my pap- 5 over, 0 up); we took about 1/2 oz out.
What I have is a smooth, controllable ball when the backends really jump on fresh lanes, and a ball that is usable later in the block when the mids go and I still need something strong enough (but not "jumpy") off the spot to carry. Overall, I'm satisfied with the ball, but it doesn't make me say "WOW".
Great ball, and I would suggest getting one. It isn't (in my opinion) a must have, but you won't be disappointed with it in your bag. Multiple layouts possible, with surface adjustments coming easily to fine tune the ball to your game.
And for $75, a pretty unbeatable price!
