thanks very much for your detailed analysis.
now I would have to decide which Quad? the 76? or the 71?
I have 74 kilos what would you suggest?
My smaller sail is 3.7 and my bigger 5.3, they fit perfectly with the quad 76 but I worry a bit about the high end, probably the 76 is too big to sail with a 3.7 or even 4.0 sail.
