Chitown, I have two friends that track relatively high, and have had success using pin under drillings/ The only stipulation is that i have used low holes, that are decent in size, which have lowered the track flare. just give yourself ample side/thumb weight to play with when you kick the CG.
The reason why you can place pins low on assym balls, is because they lower track flare. I do not know the cause, only that my PAP on low flaring assym balls is lower than on low flaring symmetric balls.
