what if any changes to the drilling layouts would you make if the bowler has a high track and not  a medium track.  All of there layouts assume a medium track.  I have a pap of 5 3/4 by 3/4 up.  I was thinking of drilling a reckless using the big cranck layout.  I'm concerned about the ball flaring over the finger or thumb.  in the past i tried using a rico drilled ball and it rolled over the thumb.  any help would be great.  not sure of my axis tilt or rotation revs and speed match up.
