Some info that could help.
Kind of a updated version of the calculator below, just with out the calculator part
Click for Bowling Ball Surface Adjustment Table
Heres the link to a pdf of the Ball Surface Friction Calculator:
Ckick for ball_surface_calculator.pdf
This info is a little dated (from the Urethane early reactive/particle ball times) but a good comparison piece.
Ball Surface Friction Calculator
From Ebonite Tech Center:
Read through each of the five categories below. These are the important topics to consider when
choosing the proper ball surface friction for your style and lane condition.
Simply note the choice in each category the variable that fits you. At the end, add up the five numbers
and compare this sum to the chart at the bottom of the page.
This chart is only a guide. You may have to fine tune the final surface texture, but this will provide you
with a starting place.
Having a trained pro shop technician assist you will pin-point the proper selection.
