visionary immortal pearl weight hole placment, please help
« on: July 02, 2013, 12:20:04 AM »
Hello all, I got a immortal pearl and redrilled it pin over ring and cg 1/2 from the midline and the (virtual mass bias)ended up 1/4" right of the edge of my switch grip thumb edge.... Now I was tempted to motion hole this ball ,but was advised that since this is a anti-mass bias ball its not a good idea.... So is there a special way you have to place a balance hole on the immortal pearl? Or is the standard gradient line balance hole placement what I should use?
id like some help from those that are more knowledgeable on weight hole placement to help me pick the correct spot whether it be p1-p4 or maybe a mo hole will work ...but please give suggestions ... Thanks

I'm looking for the most backend & drive through the pins...
pap is 4 9/16> 1/4^
475 revs
45* rotation
15*tilt

Well first off let me say I got rid of a pin under bridge VMB was in the 4 position and that ball was clean and strong but it was a fourth drill (no plug in track)....and it was at 4000+polish at the same house I bowl at now... So it may be that with my specific style the ball may just be getting into its roll a tad too late...
