I have one and it is one of the most versatile pieces I've thrown in a while. I'm RH, medium revs (300 rpm), fairly low track. Mine is drilled with pin above bridge, roughly 4" to pap for me, MB kicked out. I've found that less surface works the best ie 4000 grit or higher, and/or polish. The ball gets easy length, very readable in the midlane, and a strong arc on the backend. I've found a lot of success on harder shots with this one.
I think it's a very versatile piece. Try your favorite drilling, and match the surface to the conditions you want to use it on. I think you'll be pleasantly surprised.
