All of these drillings were recommended by my proshop. I do not know all my stats...My PAP is 5 1/8th over and 1 up......15-16mph...350-375 not sure of tilt, axis between 45 and 60 I think. My proshop says I need help getting the ball through the heads, that is why the 60+ drilling angles, he also told me around 100 total angles +/-20. Since he has been drilling my stuff I have felt more comfortable reading what the ball will do, except for the 607A.. When I need the ball to read a bit earlier, I take the surface down a bit.
I have only had two balls pin down in my whole bowling career, A Cell and a Street Rod Pearl, both balls rolled up too early, even the SRP. So I had both redrilled pin up and had success with both.
I am just learning about drilling patterns after all these years. I always banked on my proshop to set me up a ball that would nfit what I wanted/needed.
I average 210ish just about anywhere and when i struggle its usually with my timing more than anything else. I did avg 218+ for a few years back in the mid 90's, then i quit for over 10 yrs. I just started bowling again in the beginning of last bowling season
