ya i was going to ask that too sean. can you do a straight ts front roll brian?
like sean said you're definitely coming off the wake wrong. look at this:
why are you looking at the boat? you've already turned your shoulders. now when you go for the grab...
the board is moving away from you, the rope is moving away from you and way over your head...and it's a mess.
definitely you should work on just standing tall, getting your pop and then rotating forward towards the opposite shoreline. just like a front flip off the side of the boat. in fact you might want to try that - try doing a standing front flip off the boat holding the handle with someone holding the rope. that's the rotation you're looking for.
