The pulleys give them a mechanical feel, with quite a lot of lag following bar input. They have a tendency to backstall when riding down the line.
I gotta agree with suze on this. Construction was pretty decent though and the bar was good, very similar to the SS bar. The only negative about the bar is the depower knob, it is ridiculously small and difficult to grab. Simple enough to switch it out. Sweet chicken loop tho. The kite sits great for freestyle/wakestyle stuff but no bueno for waves. I though it is supposed to be a wave kite? Maybe it would be good for offshore surf conditions
