I have one, pin above ring finger and MB about 1 3/4 inches right of the thumb. It gives good length and an almost but not quite snap on the backend - very controllable with good carry. I would NOT sand it unless you are a high rev player as it will start up early and then not finish very hard on the backend. For me, it is particularly good at playing up the boards even after there has been some lineage on the lane and some of the oil is gone. I never have any over/under issues with it. In my opinion, it is ideal for the 2nd or 3rd game of a first shift league or for a second shift league, but on fresh oil there are better options. I start with a pin over fingers Virtual Gravity throwing over the 13 board in my house on the fresh, and after about 2 games I can often pull out the TF and play over that spot with it depending on how heavy the oil was at the start.
