I've been winging an 85 cm in the gorge, but am interested in trying shorter as I become more downwind focused with the parawing. Any opinions on 75 or 80 cm in the gorge? Is upwind through the short and steep waves still OK?
I like 80cm for the Gorge ; 75 is a little short especially if you're super lit on the PW. You just don't have the length buffer in big gusts edging upwind through steep chop or maching down wind, but many people like the sportier feel if they can keep the foil in the water. You'll adjust to either really.
