I think most flat kites will spin on one line with less pull. C kite will do a big loop and pound you into the water face first if you're not ready for it. If you are going to try it, you may want to try it on the flat kite first. I was doing them last night and landed one wrong an sprained my knee and ankle. I'm limping today.

Not sure if thats true of all flat kites and hybrids, just repeating what I've read on kiteforum.
