hey, I have a cherry vibe 15 lbs 3 inch 3 oz top, drilled pin bewteen fingers stacked directly below.  Love this ball.  medium speed (16 or so) and medium revs, mid track, standing right foot at 20 break point about 9.  I was thinking about an onxy vibe same specs, maybe drilled pin under ring cg kicked out about 20*.  how much stronger would this be?  just looking for about 2-3 more boards.  Any help is appreciated.

Mutant cell
Magic action
Cherry vibe
14lb agent-first ball I ever owned
skull and cross bones
rogue cell- not my thing

pin drilled above and between fingers compared to below ring is probably going to be about an 1" closer to pap. that along with the stronger cover of the onyx, you will definetly be stronger than a couple of boards and much smoother
