In my experience the higher the aspect ratio the less surface area you need to make the foil work.
Depends on what you mean by "making the foil work" and your power source to lift the foil. I get that everyone is super excited about a new foil and direction for Armstrong but facts are stubborn things.
Despite people's individual reports, the fact remains that higher AR (for a given SA) means higher stall speed. May not matter if you have a wave pushing you but for winging, going up on AR requires more wind/wing (for a given SA) to achieve lift off.
For those who like to repeat the canard that SA does not matter for high aspect foils, sorry but the laws of physics have not been canceled.
i think there are aspects of foil performance that can't be captured based on two specs like AR and SA. There is also the practical application/sensation of foiling w/ all these other inefficiencies. but I've had different foils from different foil brands that have similar outlines and specs that ride completely differently with different wind/speed ranges. the two ~AR10 foils I've used have been surprisingly easy to get going and both had glide unexperienced with other foils I've used.
For my W1000, I don't know if there's a huge difference in takeoff ability b/w the 790, 950, and 1000, but I would have to do side by side by side test. My Fanatic 1750 and 1500 get going earlier and more easily (at least I believe this to be the case).
I was expecting the SAB W950 and Fanatic HA 1500 to perform similarly, but they are totally different and both very nice.
