Great video!  But if I could make some recommendations for improvements:

1.  On your side sommi's (or Arabians), you'll gain more height if you hurdle higher before you flip.
2.  There's a reason why there's a tape line on a vault spring board...that's where you want to aim your feet.
3.  Don't try to twist when you hit the spring board because that will make you land off center (falling/running off mats).
4.  When you hit the spring board, you're suppose to not come straight down on it, rather come in from an angle (feet forward, body straight back at about a 30 degree angle), like this crude little drawing:

--->     \     (jump)
    /--------  (vault spring board)

not like this:

--->      |    (jump)
     /-------  (vault spring board)

....this angle allows for more height and spring which means you'll actually be able to stick that double front!  =)

Hope that helps....
