Well much to my chagrin I found that after all these years my equipment has been drilled wrong. You see I'm a full roller but balls have always been drilled with pin near fingers. Had Infinite Theory drilled by a different person than I normally have and I was pissed because I saw he put pin near thumb. I'm like "what in the world did you do?"I asked him why and he told me because I'm a full roller and he showed me instructions that come with every ball mfg co. He said to try and if I don't like then he'll give me a new ball. Well four games later...236-248-268-230...what gets me too is that I was getting these games without any effort. Lately it seemed I was fighting with the ball. Oh BTW I did bowl one game with my new Theory drilled old way...168. What gets me too is that for many years I've been booking 205-210 but last 5+ years only in mid 190's. So needless to say I guess I'm getting my equipment drilled differently...
