Now let me make it clear I'm no looping expert hey. Just whack it in here and there to add to the dogstyler motor cross style riding. If I was I'd be on C kites! I'm to old and lame to really push the looping envelope...well maybe to lame, shouldn't blame age hey.
I'm borrowing from Toby really, just recently of kiteforum to, he explained well what to do. Been doing it for years but never really thought about it as much and paid a few painful prices for it to.
Now lets say you are going out to sea in WA on a south wester, left foot forward. You send the kite from say 10 to 1. Lets say you redirect to early and the kite is back over to 11, loop the kite back to the right (downloop, back hand pull). Or if you haven't brought it back cause you are hanging upside down with your tongue hanging out enjoying the view, forward loop it back across the 12( forward, left hand pull). If you do this with enough height you will get a helicopter loop, lower down it becomes a common place down or forward loop. Do it before you reach the summit and it becomes an actual loop...the type I choose not to employ as I'm lame.
Thing is with the edge, doesn't matter which side your kite is on and how far it, redirect hard at the end and you will be that horizontal paraglider landing anyhow. Only when you go real huge and find yourself all out of sorts due to stupid body rotations and board grabs that I need to even consider this. The edge is so forgiving on the landings. I just loop cause why not. I mainly just loop down the line on the waves really to get to certain sections with speed. Or if I'm doing a transition and want to go the other way...
Back roll back loop, get your body slightly rotating when kite reaches 12, before you pull the trigger I find. Remember it is high aspect, it won't pivot loop like a C kite. Their will be some arc in its trajectory.
Practice first with little height, even through your forward hand in the water as a kind of break. But commit, get your back hand at the end of the bar and crank...also do it in one motion...meaning from low down, bring to 12 as you rotate then apply the loop...the edge wants kite speed ( as all kites do) but the edge will loop closer to a pivot the more speed it has. If you stall it and then try and loop and the arc will be greater the power will be greater the consequences could be greater.
Anyhow that's my take on it, someone might have something better and more accurate to add. As I said I'm no expert in this style or any really for riding and only been on the edges for a short time.
But how bloody good are they!!!!
