Unusual track line on ball.

OK, I too have changed to be more under or behind the ball and now my ball rolls over the thumb hole a lot of the time. What am I doing wrong?

You aren't doing anything wrong. If the change of release is drastic enough the change in your PAP can be drastic enough to cause this. This can be especially true if the ball wasn't drilled to your PAP to begin with. Plug and re-drill based off your current PAP will fix it.

You may be completely flathanding the ball - try a little bit of axis.

Sounds like you have just changed to being a fairly low track player. No biggie, just a different way of throwing the ball. I tend tyo be a higher track player than that, bu like the old saying goes, "whatever works..."

The local pro shop owner who also happens to be a 220 average bowler watched me bowl and then inspected the ball - he convinced me it's the ball return belts making the track which didn't make sense until I realised that the weight block probably orientated the ball a certain way as it rolled down the tunnel. His explanation also made sense as the material buildup along the track was definitely not oil, but more of a rubbery substance and there was evidence of a more traditional ring formation.
Amazing what a bit of careful detective work will reveal!

Wow after all that ha ha ha good find. Our local house back splash and ball return always leave soft rubber marks on our equipment. Most are dang near clear
