I ride a 7 foot Christenson Ultra Tracker and a 7.5" Skip Frye Flex. I love this board and fin setup but I want to tighten up the turning radius a tad (cutbacks, bottom turns, bottom turns). I get enough drive with this fin, tried other fins that accomplish what I'm trying to achieve with this fin but at the sacrifice of everything else great about this fin. If you have experience foiling fins, where would you take a grinder to this, and I am talking about tiny intervallic adjustments at a time, testing the board, and repeating until I (hopefully) achieve the desired result).
