I have to agree with Scoot, on the Inertia.
I've heard a lot of good thing about the ball, from people I trust.
I have 2, undrilled 15# Inertias, and 1 14# undrilled Inertia.
My Equation2 is 4000 grit Abralon w/ 2 coats of Beans Sauce on it.
I really long and strong. Use it as a spare ball, also.
I will drill up a TEMPER, and give it a try.
I have 2 15# Risings, LH drilled.
They aren't mine... one has 2-3 games(suggested pin in palm drilling), the other has NO games (pin an inch above ring finger, looks like the cover is lowered to 600 grit).
I was thinking of plugging the thumb on one and trying it.
I will eventually pick up a Rising in 14#.
