RE: isonic 122 or isonic 133?
Thanks for your swift reply Ian.
My smaller board is an old F2 Thommen 270III (92 litters) capable of carrying my 6.6sm sail, but not my 7.8. As I understand from your comments, I would be better off by buying the iS 122. Am I correct? On the other hand, I really enjoy being the first to plane in marginal conditions and my 9.2 sail, without being on a formula board. I suppose that a bit of pumping will do it on the 122 as well...
