I have a thruster rotating fin board. It is 6’4" , 19 3/8" WP, 2 1/2" thick, wide point a little forward, 13.5 inch tail, Patagonia point blanks board. It has been retrofitted with
rotating rail fins, and initial tweaking is done. If this is reasonably close to your size and you are interested in test riding it for a few weeks lemme know. Initial feedback is positive enough to solicit second opinions.
