A small low aspect wing is just a low aspect wing for more wind, sure its a little faster, but you'll need a lot more power to get going, and the improvement in glide and speed isnt as big.
Remember, a high aspect wing gives about 1,5-2x times as much power / lift as a similarly sized low aspect wing. In the end, a 1100cm2 high aspect will give the same, if not more early lift than your supercruiser, with more speed and more glide through lulls. The downside being its more direct, and has a lower stall speed due to its smaller surface (although you're traveling at different speeds aswell, so always wondering, would you rather have a foil averaging at 25kph with 15kph stall speed, or a foil averaging 35kph with a 20kph stall speed? The second one has a wider range of use and allows for more loss of speed in the jibe). A low aspect wing is soft, you won't feel much if you get a gust or a chop, whereas a higher aspect wing has a little more direct / agressive power.
Also remember, if wings are similarly sized, the stall speed is similar, although the performance in terms of speed and lift doesn't at all have to be.
As for the AFS, i've tried the 85 with F800 (standard freeride) wing, and clocked around 45kph with it. A supercruiser would never go that fast.
Thanks WOH. I don't think this is something I have fully understood until now. I must admit that I have been a bit focused on surface area, thinking it was the key stat for lift. Kind of like in windsurfing we talk board volume not length.
From a riding perspective I seem to get irritated by the absolute stall speed more than anything else, and it seems like it takes quite a bit more sail to keep a lower area high aspect wing (i65) going through the lulls relative to a medium aspect medium area wing (i76). But that is pretty subjective.
