Yes, I was in a hurry to get in the straps, when the board was geting lots of speed it was very hard to ride otherwise, very jumpy. On flat water it's easier but that was not the case. Anyway, I guess that with lots of experience you can ride the GO 180 on sea and lake in big winds but much more difficult than a pure freeride/slalom board.
I think I'll keep it until I master it and also buy a freeride for chop conditions.
As for the big sail, I'll go for the swift 9.0.
