I'm with ceaser on this. If anything I'd get rid of that annoying fifth line and drop the rebel line myself....ooooooh controversial I know, I know.
Switchblade / core (the new X3 looks nice hey) are all good jumpers but they lack that little more aspect the fuse has.
As for the edge, its a full blown race kite and takes a lot more timing to jump properly. What I have found it the edge will go big and long but it does this best when you are really really lit and needn't move the kite much, when loading and boosting. Thing is the incredible range of this kite allows you to do this as it keeps its forms right up to a riders top end given their weight.
But it doesn't like current and it doesn't like waves...which go hand in hand.
The fuse/rebel is much for forgiving in those conditions, does not require as much board speed and power to jump big and will start jumping earlier....you can jump with little notice and in a short space of time. Important in choppy or wave conditions. The edge require you to line it up to really go big. But when you do watch out!!!! Can't beat the glide that's a fact.
So I share ceasers disspointment and I don't even ride fuses and not longer ride rebels!!
