Backflip, Tantrum---help

First off- I just thought it was a backflip but i guess in wakeboarding a backflip=tantrum? At any rate I need to get some points on my backflip.....once and only once have i made it back to my feet---and when i was all around on my feet I LOST THE ROPE(AHHHHHH) and i have not been able to duplicate that since then...so give me some tips on getting around...i either put my nose in the water or i just friking screw the pooch....HELP

THANKS
