RE: Highwind / Lightwind definitions
IMvvvHO the chart was useful just the way it was. A rough guidance for board selection. Of course, one could add as much detail as he wants, but inevitably he will be adding complexity at the same time.
So, I'd leave the chart as it is (only I suspect that in quite a few cases a "consistent/inconsistent wind" guide would be even more useful than the "light/strong wind" one). Rather, I would add detail in the specific pages.
Some time ago I suggested, at least for specialistic boards, to specify in which conditions a board is first choice, and what a given board is best at.
