Day of experiments, started on my TT forumula board with a 9.6m, what a waste of time only got 24 knots, the board didn't like either of the fins. The wind picked up to so rigged my 285 and 7.0 (need to go and pick up my 7.7 and 8.6 from the shop), got some good speeds. Wind droped and managed to borrow Peter Crock's forumula 159, had some good runs with 60cm fin.
