I still think it is extremely individual.
I havent found it easier on the bigger wings, and I got from just over 500 cm2, through the midsized 7-800, to the 11-1200 cm2 sized.
Because you ride with more power/kite with a smaller wing, and you dont change feet while going downwind but either at the start of the jibe, or at the end, it is in my experience not important with wing size.
Going a tad faster with a smaller wing, usually makes the foil even more stable for switching feet in fact.
So for jibing in itself (switching feet while carving) I dont see much advantage, if any, of the bigger wings.
The kitelift is used slightly or hugely when switching feet, and the kite lifts more with smaller wings - I think that is why it doesnt matter much which wing size?
Kami does find it a lot easier, so might be individual, or the individuals specific technique.
When around 700 cm2 and up, I dont find ANY difference at all.
With smaller wings there might be (or not), but only rarely ride the small wings nowadays - only for jumping with straps.
