Need some help with my tantrum.

Hey guys

Ive been riding for about 3 seasons now and i just landed my first invert; the Frontroll.

Landing it was a great feeling, and i can now land atleast one of them each set i do (When i landed my first, i immediately landed another 2 straight after it 0.o)

Now, i decided i should learn the damn tantrum finally, after doing a few hopeless try's... i just cant seem to do it right.

I'm pretty good at backflip's on the tramp, can do em with spins, like 5+ in a row, without more than one jump etc. Theyre just easy for me on a tramp.

The thing is, i cant seem to get it right on the water...

Ive watched alot of tutorials, and they all tell me i should feel a "trip" on the top of the wake... But i dont...

Im not sure about what im doing wrong, i cut as hard as i can and try to maintain control @ the wake...

I have a vid from last season, with my best attempt (Look at more of my vid's for worse try's :P):

I just really want to land this trick soon... and i know i can, its just 1 thing im doing wrong and i hope u guys can help me out with finding it

Thanks

Bob.
