So i decided to polish one of my Pitch Blacks as they have been burning up early and leaving alot of corners. Saw a few posts and people loved their Pitch Blacks more after polishing. Well, Im going to join that group. 10 minutes in a Lustre King and a new polished Pitch Black emerged. Had to take some alcohol to it to get some of the residue off but off to the lanes i went. Practice was great but i decided to go with my box finish Pitch Black to start with. 217 with 3 10pins and 1 7pin. Decided to switch since i was hitting pocket but not carrying. Out comes the polished Pitch Black. What i saw was a ball that still wanted to hook early but due to the polish, glided thru the heads perfectly, saving its energy and giving me just enough finish to comfortably carry corners. 246-268 last 2 games and everyone on my pair said that the polish makes this ball soooo much better. If you have been contemplating adding polish, dont hesitate and just do it.
