Instructional video time.
I've posted this in the Aerials thread already, but I know how visual we men are.
The folks at MOBgroup.TV have put together a quick video of part of the video contest:

Back to biz...if you find a good clear surface three, then step your way through it paying attention to body placement, board alingment, head position the video can really help point out what you're doing wrong.
WAlove, check out Mark Sher's backside 3 in this video...I don't know about anyone else, but I can barely turn backside, yet alone throw a surface 3.
