First rigged the 6.2 but I clearly overestimated the wind speed. I returned home and rigged the 7.0 but after a while I didn't feel any real speeds coming so I did some wave surfing. During this wave session I felt the 7.0 calling so I returned home again. It was a great slalom session but every time I tried a speed run the speeds were dissapointing. Could not find the speed in speedsurfing. Next time I'll trim the sail a bit differently.
