Hey Andrew,
From my experience w/pin over mid finger(various rg's and covers), it really pulls up quick and stabilizes the backend. It created a very smooth overall look and it looked nice on flying backends or O/U shots. The only trick I see on the PG in true dry is to get it far enough down the lane to help store some finish or it might quit on you a little. You have pretty good speed though, it might not be bad. Let me know if I can be of some help to what we discussed before bud...
IMHO, the tradeoff for controlling the backends is not having the right room down the lane. One last thing, it also might make you clip the fingers or thumb. Hope this helps some...
