Well, here is a little secret that I recently learned when drilling mass bias balls for lefties. In order to achieve a certain reaction based on a drill sheet, you actually need to swap the pin and mb with each other. So for a rightie, one would put the pin below and a bit right of ring finger with the mb on VAL for early forward roll in heavy oil. For a lefty, put the mb under and slightly left of ring and put the pin on your VAL(vertical axis line). If you dont know what your VAL measurement is, have your driller measure your positive axis point. Where that lands, draw a line vertically and that is your VAL. Good Luck.
