Just had my PAP re-checked and it went from 4 3/4 over and 1/2 up to 3 1/4 over and 1/2 up. Looking for suggestions on drilling a sublime for this.track and rev dominant. My.favorite symmetrical ball now is a Venom.shock and with my new track it maps out 2 1/4 X 0. Yes the pin is on the VAL. This does not seem.like a good layout buy the ball rolls.pretty good. I hesitate to drill.another ball with this layout. Common sense says something like 5 X 30 would.be better for a low track rev dominant bowler. Am I missing something here? Any thoughts.would be appreciated. I am about 11 mph at release, and I assume.have a lot.of tilt.with the low track. Thanks.

This is not a layout idea, but a suggestion based on a recent personal experience.

Recently I noticed my track was lower than normal, so checked my PAP, and sure enough, it was.  My experience told me to get the thumb out earlier so I spent the next two weeks focusing on that, and better ball motion returned. 

If I were you I'd try that because the results were immediate and obvious.  Staying behind the ball longer and freeing up the arm swing were critical to me using less grip pressure and fixing the problem I had slowly gotten into.

Layout is third down the list of importance to ball motion behind 1) the bowler's speed, release characteristics, etc, and 2) surface texture of the ball.  When we track that low and have so much tilt we "paint ourselves into a corner" so to speak, and limit what layout options are there. 

If you train yourself to work on #1 above then your bowling will open up options rather than limit them.  Just an idea from personal experience and not criticizing anything about where you're at.
