I've been using 5.5 and 6.5 sails as this is all I can currently borrow. The 6.5 was a new tushingham storm and a real dream to handle. I'm a little hamstrung in that I can only borrow the kit on a fixed evening each week and have to make do with the wind speed available. Hence a new board (and new sails - sorry advice request on sails to follow) would obviously allow me to be a little more discerning and avoid too light winds - I'm on the point of getting off and pushing in light breezes out of frustration. I think this is because on the higher wind evenings the adrenelin rush has kept me wanting to push my boundaries more.
