RE: Problems going upwind
I've now tried the straps in the back and outborad psoitions and it works! It was, as Roger suspected, me pushing down (especially my front foot) on the board rather than putting the pressure on the side of the board. It was rather quickly I managed to go higher but it wasn't until the wind picked up and I was able to get (also) the back foot in the strap that I got the fin lift for the first time. Really thriliing and great experience!!
