Came across something I've never seen before yesterday with a customer. Here's some details on the bowler.
1-Two finger bowler but needs the thumb hole drilled as he uses thumb for spares
2-First ball purchase (has always used hand me downs)
3-New ball is a Maverick Pearl
So I measure him up and have him throw some balls (with stuff he has) to get that data. You can hear the ball rolling over something going down the lane, so I'm thinking full-roller initially. Ball comes back and the track is rolling directly over the fingers but in the opposite direction. (pictures attached) Can't say I've seen that before, any ideas from the ball drillers out there?
On edit - Pictures are tough to see, but the track is going over the pin and fingers in the picture and a straight line there after approx. 45 degrees away from the thumb
