I have a bowler that I have to drill 3 new balls for, he prefers a layout that finishes strong, he has these 3 new balls, Hammer Scandel Pearl, Radical Fix, and Roto-Grip No Rules Solid, the Radical Fix has a 3 inch pin the other 2 a 4 inch pin. Any help with layouts for these 3 balls that would all give a strong finish would be appreciated. He bowls in many tournaments these balls are not for house patterns.
Specs are
Release speed 18mph
Tilt 13 degrees
Rotation 60 degress
Revs 210
PAP 4 1/4 x 1 1/2 Up
Left Handed
