u want to stand tall before u release from the wake... but u dont want to stand tall to early. i stand tall as late as i can before im in the air
oh yah, and bring the handle down tight into your crotch (do this at the same time as when u stand tall
the 3 most important things in getting air are:
-edging ALL the way through the wake (no letting off your edge!)
-bringing the handle down
-and standing tall.
u will lose a lot of height by not doing one of these things! timing is a bit weird at first, but once u have it... you'll never lose it!
