yesterday I have a low wind foiling session with my new 14m enduro, which replaced a 13m edge.
my feeling is that i lost upwind, speed and jumping skill, but at the same time, i can get going much easier and keep going at much slower speed.
turning speed improved, and drifting vastly improved over a 13m edge. Also misstimed jumps are much easier to recover from with the Enduro 14m.
hangtime and low end is about the same. the 14 m enduro is lighter than the 13m edge, but edge makes up with its higher AR.
But overall my feeling is that if you only foil (i also like lightwind twintipping) a 10m enduro will give you all you need in light wind, for me is the best balance power/turning speed wise, and then add a light foil kite for lightest winds.
