Today I managed to at least give Twan a run for his money. When I left I had a better Vmax (42.3), better 2sec and a better 500. The average and 10 secs were not quite there but I at least have the excuse that I sailed about half the runs of him. 

Really like this set up with XF 90, 6.2 Firewing and 30 Fhot RS3. Has enough top speed to challenge the speed boards, but keeps going better through the lulls and over chop. My best 10 second run had a huge lull just before, but thanks to the slalom board I could keep the speed going and then accelerate when the gust hit.
