Just a general technique question.
I'm finally getting some pretty mad speed on an edge and I find that probably because of the combination of my 100kilo body having a fairly big intertia and 14m kite that it can be very difficult to slow down. When I couldn't really edge well I always used to just fly the kite up high, but obviously that just makes it impossible to edge.
The only option I can think of is to edge even harder? But I don't really know how to do that, is this when you start putting your bum down toward the water?
The reason I wanted to know this is because I am trying to learn to do a clean reverse, I find that if I send my kite back to 12 to slow down before reversing one of two things happens
a) I lose my edge, my board hits some chop and I faceplant

OR
b) I just get lifted into the air... although its fun, its a bit hard to land when trying to reverse in the air.
Is it more to do with the gradual movement of the kite back over 12 and to the other side?
Help much appreciated
