That is an interesting track you have there. I have a girl that I coach that is very close to that PAP. She covers a little less surface with her track though. As far as drillings go, you deffinately need something a little different than your average joe bowler. Me and my ball driller when laying out balls for this girl usually go an inch or 2 above the fingers and put the CG/MB pretty negative. This lets her ball hold some energy for a snap. Right now the way you have that ball layed out is like my lightest oil ball. It is impossible to make its flip. That is most likely why you are having trouble on oil.
