A light (3 strut) kite that is fast through the air is better than a bigger heavier kite that is slow to turn in light wind. A fast kite will build apparent wind much more efficiently than a slow kite.
Hmm...
I've flown light, fast kites of any number of struts that whizz around the sky doing sweet F.A. They turn on a dime and are super responsive but gutless.
Kites that are fast across the window make a little more power but what you really want are kites that make power on apparent wind: these are usually higher aspect ratio kites like Crossbows, Edges, Drafts... race kites. Well, until you want to loop them or do other interesting stuff.
Some gear and conditions require high frequency sines (fast turns, long strokes from the water to the zenith) and some only need gentle sines.
Key point - keep the kite flying and don't choke it.
