hey andrew, we meet again! ;)
i landed one on my third attempt and i have to give all credit to the higher education dvd. but then i landed hard on my next couple of attempts and decided i really wanted to learn 3s.
the keys for me in order of importance (to me) were this:
1) handle position
2) ear to shoulder
handle position - both hands on the handle, the handle at waist position and held in the same position you would cutting in; arms relaxed but fixed. as charlie patterson says in hl, you want your arms to form a right triangle between your elbows, the handle and your shoulder. this handle position remains the same thru the entire trick.
ear to shoulder - as you stand tall and leave the wake, put your lead ear on your lead shoulder. this should initiate the front flip.
if you stand tall and get your pop - initiate the flip by putting your lead ear on your lead shoulder, and hold the handle in that 90 degree locked position - you should just pop up and rotate over.
as for the crashes, if you let go with one hand or if you don't fully commit to putting your head on your shoulder, you may under rotate - i did this a couple of times, stalling out my flip and landing on my side. hurt a bit, but nothing really damaged except my courage.
i recently decided to start trying these again as i think they're a pretty cool looking flip - and one you don't see a lot of people doing. and they look especially nice grabbed of course.
good luck with it. let us know how it goes!
