Apperantly some seem to think that they are using plastic on a normal volume PBA pattern as I see by the recommendations to alter the surface so some rediculously low grit. The PBA is altering Cheetah so that plastic WILL HOOK regardless. Maybe some are joking about it, or NOT, but the fact remains if you've ever bowled a plastic ball league or tournament the shot is altered. Yes there will be some surface adjustments to scuff the ball up a bit, but I highly doubt there will be anyone throwing their plastic ball at 400 or less grit.
