hi ian,

i'm assuming that it's either a "pro shop day" or a "5 points to
better bowling" seminar.  roto grip in conjunction wth the pro
shop organizes and offers them.  having never hosted or been
involved in a "5 points" seminar, i can't offer any help there.
however, in conjunction with my shop and the center, i will be
hosting a "pro shop day."

general itinerary: one hour of "classroom" discussion by hank
boomershine describing the lastest roto grip balls, core design,
ball motion, cover design, etc...then each participant receives
a one half hour instruction.  if it's not either of the above,
then it could be a "regular" seminar organized for the pro shops
through the local distributor.  

hope this helps.
