Pff ...
67cm wide board and 39cm fin were way too small for mine 85kgs.
Getting upwind was really hard, so not much fun.
At the end I took Pat's Falcon 124 (08') with a RS7 45cm fin. Even with less wind this was much more fun. 10s run 3-4-5 are with this combo. Thx Pat!
But ... A day in the sun, on the water, with a lot of friends, is still better than a day at school or on the couch ;-)
