i drilled mine today left it in oob condition. pin above bridge and mb just right of thumb hole no balance hole pretty basic. ball is a monster i started out throwing 20 to 5 and on a fresh med heavy 44 foot pattern. after 6 shots had to move 5and 5 left i got more push and more backend this ball is an oil eater, absolute monster! i am probably gonna polish it. i also drilled a wreck it and the wreck it i played 15 to 4 with very strong backend reaction never had to move with it for three games. both of these balls are great in their own right cant go wrong with either.
