 BTW, I also asked about surface adjustments to a factory polished SCB in lieu of Trizact 35 micron pads and they said this:

 "Thanks for checking out our website, hope you've enjoyed it. Trizact Pads can be purchased through distributors, i.e. Jayhawk Bowling Supply http://www.jayhawkbowling.com/Products/taxi.html You can also wetsand the ball to 400 grit for similar results. If you have any further questions, feel free to contact us again anytime by e-mail or phone 1-800-Lane No.1 (526-3661). Thank you for your interest and choosing Lane #1."
 
Sincerely,
