Over doing it

I started wake boarding about a year ago, coming from a kiteboarding back ground. Things are going OK but I have hit a bit of a wall - everything I do seems to land me in the flats with lots of line tension. Roll to reverts, raleys etc no probs but trying to get consistent with mobes and whirlys, I seem to have way too much line tension. Even basic back rolls I cant land down the second wake at all - any tips on how I can slow it down a bit? I am getting hammered with mobes and the handle is getting ripped out of my hands - same with tantrum to blinds too.
