Hey dog breath,
Try and forget kiteloops for a while ! My biggest jumps are never by looping, theyre always about timing as westwood says. Build your speed up (slightly downwind) then grind hard up wind for a a few seconds then pendulem the kite back to 1 oclock to pop up. While in the air, redirect the kite (as u prepare to land) forwards to about 11 oclock. For a smooth and controlled landing - always aim you board downwind. Obviously, remember to pull hard on the bar as you swing the kite back towards 11 oclock - and keep it pulled in till youve landed.
Hope that helps.
