I normally ride a huge 1200 sq cm wing and recently I took my friend's levitaz element foil for a test ride.
It's pretty much counter-intuitive but riding a small wing (680sq cm) generates so much apparent wind that I almost instantly got overpowered using the same kite in identical wind conditions.
Which brings up a question, that apart of the obvious fact that you instantly pop up on the foil when using big wings, what are the other benefits?
The way I kind of see it now is that small wings move faster, create less drag and require smaller kites, but people still seem to gravitate towards surf size foils.
I'm relatively new to foiling so I wonder if anyone shares the same experience?

Of course, "fat" low AR big wings are really draggy, eventhough they turn well and easy to ride.
But the same wing say twice the size, has almost the double amount of drag, at the same speed.
When going fast, they have exactly the double amount of drag.
They can never ride as fast, nor glide as fast and free, and will feel more draggy than smaller wings.
The fuselage and stab and lower part of the mast is a constant drag of course, so the total drag is not doubled, no, but it can be felt immediately if you change wing size both the ups and downs.
You are right though, that you can, on bigger wings, to some extent get rid of some drag having high AR thin profiled wings, and they feel "light" and free, compared
The downside is they will turn slow because of the span, have less windrange (less "good" AOA range), be more fragile, and risky for jumping
Roll stability is better yes, but a disadvantage in turns and not what most seek.
And pitch stability will be worse I would say, you got similar more torque with a bigger wing.
Same thing goes the other way, for race wings, they are not necessarily smaller than our small/medium wings, but have less camber, so a lot more stable and only need really small stabs.
