too light, too tight, and me too heavy. I went for the 6.6 for some efficiency but was under powered, using the same size as my lightweight team mates :). Stuggled all day to only just beat by 2 knots my results from yesterday on the 8.5! Probably should have gone the 7.5 but then it might have not been as efficient on the very tight course. Did my 2nd,3rd,and 4th fastest runs on port tack sailing back to the start!!!! - Thats a tight course. Anyway its all good fun.
