That's what I mean eppo. Floaty hangtime (mostly downwind) vs a vertical high jump (with horizontal option when desired and looping).
@rcr46401: mate I am not skinny, I am just lean and not very tall

I am flying a 6m kite in 40 knots winterlies, no problem. Just boosting high. Probably being able to handle a fast moving kite which indeed develops its power when flying across the window enables one being more experienced with regards to what happens if the kite is moved, intentionally or by mistake. Bit like a sports car vs a truck, more dangerous but more fun. But some prefer the Hummer.
I am not implying you don't know how to fly Edges etc and I appreciate you may need that extra power to really have fun. Luckily this sport is about what the rider likes and not what others think of it. It is just that most of those I see around here would probably be better off (and jumping higher if this is what they are after) on a slightly smaller high performance kite than purely edging hard for two hours trying to be in control of a monster kite and expecting all others getting out of their way as a) they cannot change direction quickly and b) they need all the space the spot offer to do their long distance floaty "jumps".
@plummet: I hear you. Impressive that you can go higher with the Edge vs the C4. I am sure a few others I see on both have it the other way around. But if you can edge and load the Edge properly and throw it as you can with the C4 ok. Glad you agree on the higher winds as this is what we were mostly referring to.
Again, this is not for those capable and experienced heavy riders who don't have a choice. I understand the gravity issue.
