Nic, have you tried a short pin, drilled label with the pin under/slightly to the right of the ring, with the CG towards the palm..? Nothing fancy, keeping it simple, this gives you the most continuation on the backend. It works great on Buzzsaw's.
With pin out balls, pin over the bridge and Cg kicked out 3 1/2 - 4" from PAP also work great, for an earlier, more even rolling motion. =:^D
