Didn't the Instinct and Type 8 already beat you to it? I know I think of the Instinct as a C with unreal range because of it's unique method of changing angle of attack.

Regardless of which is "better", it seems reasonable that non SLE kites are going to become rare. Seems like most riders (at least here) are learning on bow/hybrids and alot of experienced riders are switching to SLEs.

It is unlikely that newer riders will switch to a C after learning on an SLE, , unless it utilizes a really good depower system like Jay is mentioning.
I agree with Jayson, that is where it's going. (Uh oh, Jayson).

I am just glad I can ride in 11knots powered on something smaller than a circus tent, and also not have to re rig on those NW coldfronts. :P
