Thanks for the responses guys. Yes, i do have someone who takes care of drilling and understands the things you mentioned. We figured out my PAP and drilled a P4 on my Lock. But, he doesn't know all the balls, especially new ones coming out, and hasn't used or practiced them on the lanes.
I like reading about people's experiences here. Think i bowl differently now then when i got the Lock. Will go out again to re-measure for sure. Appreciate even theory. I wish there was a way to try out new balls pre-drilled outside of 'demo-days' in Vegas.
