Columbia Guys,
What layout have you had success with when drilling the Professional?
We have a customer who's a high track/low rpm stroker who is very layout
sensitive. I want to stay in the 4 to 4.5 pin to PAP range, just not sure of pin up or down. Looking at a 4 x 3 or 4.5 X 3.5 placing 'mb' in strong position
just right of the thumb...it's for HPL 9000 sport(38-40') and flatter conditions with fresh backends....Ball has a 3 in. pin.
Thanks for all your help,
Bill
