RE: isonic 122 or isonic 133?
It seams like you made you mind. I just wanted to say that I have been using the 122 in really light conditions (9.0) as well as strong wind (7.7) and it really performs unreal in all conditions.
I'm 85 kg and for light wind after a few pumps the board just takes off,,,
(I use the 9.0 Code Red R2 and 44 Vector Canfire fin).
If you don???t use bigger than 9.2 then this board is for sure the right choice.
