I'm noticing that the Raley seems like it offers greater pop and amplitude than simply loading the foil down and then springing up and hanging from the wing like a windsurfer . Any jumping maestros on here that can share some technique tips to higher/stretched out raley-type jumps? Mostly riding a 72L KT with 925 and 725 foils for reference.

I generally hook in with as much speed as possible and launch off a kicker or even flat water. The good thing about the wing is you just float down giving you heaps of time to pull it back in before landing compared to wakeboarding.
Once you pop up into the wind stretch out and angle the wing slightly down wind and that will help pull you instead of just landing with no speed. Try and stretch out a little more each time till you get more confident.
that's what I've found when doing them. I'm sure there heaps of other proper methods that I can't put into words.. also check out YouTube there's that many how to videos now for everything.

Cheers, wicka! Just saw some videos up on youtube as well.
