Kite looping

I have been wondering about kite looping for a while..not as a freestyle trick but to generate apparent wind is a scenario where the prevailing wind is not enough to plan.  There seems to be two types of loops:

1. Forward loop
2. Back loop

Difference is forward loop, loop the kite upwards to generate power while the back loop drive the kite down to generate power.  It's easy to explain these moves than actually doing them.  So what learning steps can we do:

1. Looping with a trainer kite
2. Looping with a small kite in low wind
3. Looping while on a board
4. Looping while boosting

Like most things in kite surfing it's hard to bridge the gap between theory and practice as there are few safe options to practice.  Most kiters learn the tricks when they are young and stupid rather than learn them from theory. That's true for most Adrenalin sports say dirt bikes and skate boarding, how many tricks old people learn? Can't teach new tricks to old dogs....
