Come up to my local (Cairns) where our hot and humid wind combined with a heavily rockered board that is only 2cm shorter than yours and tell me that it makes no difference to the experience..... ride a wakestyle board with boots in 15 knots up here and you won't get off the beach.
The humid, that is, hot wind is gutless. My 20 knots at my local is about as equivalent to about 15 knots to those who kite around, say, Melbourne.....
I can put you on two boards of equal length but with other varying characteristics such as width, rocker, outline shape etc and the ride will be completely different in the same conditions.
come up to my spot in the hight of the season all of that means f??K all when its blowing low 30s, your hardly touching the water so it makes no difference what board shape you have
