Roger, the go is 2002, and I love it, 280 x 90. Got a Curtis drake stocky 42. I have tried the 65 fin from the formula on it but didnt like it. I am still to fresh to handle that fin. Still hard to handle the lift it produces.
I am starting over with windsurfing after 20+ years out of the water. I remember myself planing on a Fanatic lite Bat with a 5.5 mistral in 1990 or so
I would love to learn to handle the F155. It would just take time. But I am tempted with the Go 175
When I get the chance I will get a newer 8.5-9.0 sail. What do you recommend? (lousy wind)
Thanks a lot Roger
