Interesting reading. Depends on end use. Dyno 2011 has a huge leading edge hence theoretically has far more drag than say a nitro pumped to 9psi and above. But I can tell you which one is the better airstyle kite. Drag and the inefficiency it creates as I have said before is not always a bad thing.
Let's see switch create as good an airstyle kite with a thin as leading edge and I will eat my words and also buy a whole quiver of them!!!
