[/quote]well the ball doesn't hook as well as i thought on medium oil. when i throw it it just skids. But i assumed that if this ball is for medium to heavy it should have some aggresive move even though if this ball is drilled #2. it works well when the lane starts breaking down[/quote]


That could be from the pin distance being to far from your PAP if you track high, should have had you mention it in my previous post. If you had a PAP of 5 1/2 over that would make the pin distance probably 6+ from PAP. that would make for the ball having a pretty weak drill on it, along with the high finish and notorious layer of polish that most balls from the factory come with.

It could also be from the ball burning up on too little oil, but you said it starts doing well once the pattern breaks down some, which leads me to believe that the drilling is to weak for your release, or to much polish form the factory.. But a ball burning up in the midlane looks like it doesn't hook much sorta quits as it goes down the lane, not a rollout but just a mellow not want to finish hook, I experince that with some balls.

I thing I do these days with any ball that comes from the factory polished is take the ball to 4000 abralon or 2000 grit sandpapern and rioll it in that finsih first. the adjust the cover to fit what i want to see out of the ball. Juast a thought to consider, not everyone would want to do that or have access to do that, but I have been unhappy with alot of factory polished equipment. YThey work great for me once I polish them up my self, almost like a different ball altogether.
