I've only seen one thrown durring second squad of a tournament that I bowl in. The ball was drilled with the pin above the ring finger and the MB in the strong position (1" right of thumb). The particular bowler is a power player with a 70 deg's of axis rotation. He was playing inside 5th arrow with the ball and it was working well for him. Made a nice charge into the deck that's for sure. Honestly I want to drill one for myself...but am just having such a hard time getting over the poor match-up I had with the original Fuel.
