Normally on all my other bowling balls i have a high Track about an inch left of the middle finger and is slightly inverted

Well the person whose Track is right next to the finger holes would have a 6" pin to pap distance and you would have a 5" pin to pap distance and thus get more flare, we are only talking about 1" making that much of a difference and it does. I meant lower Track than someone with a higher Track than yourself, not a spinner type Track.

This is why you can't judge a drilling by where the pin is located, you have to measure from the pap. One of the guys I bowl with, he has a pin over the bridge and it is a leverage drilling for him because he has a low Track. For you the pin would be next to the ring finger for the same drilling, for me that would be 4 1/2" from my pap because my Track is higher than yours.
