need help with inverts

[Tantrum387]

ok heres my question about tantrums or backrolls or whatever. ive tried them and it felt easier to try a heelside frontflip or something because i didnt know when to initiate the rotation of the tantrum are you supposed to throw your head when you hit the wake or just ball up once you get a few feet in the aiar and just huck it??? both of those are probly wrong but help me out here
