Bought the 70l after the trying the 80l and thinking it would be great for shifty days (which are the norm in Japan, where I sail).
I got two sessions so far and while I'm very satisfied with the board, I'm afraid it doesn't match Go Foils V2 mast (if I don't bring the mast to the very back of the board, it's plain unrideable).
So I have it on the very tail, which now makes it bad to carve. So my opinion is: Excellent board but make sure it fits your foil setup
