Wondering what the name of the trick at 1:40 is? It isn't a front roll, nor a back roll, I do them all the time- i tried it today and it felt different. Its a pop with a back flip (never mind the 180 upon landing)
Its not a back roll from toe side. Its a back flip. Its different.
if what your doing is whats in the vid at 1:40 it is definitely a toeside to regular backroll. doesnt matter how vertical your legs get.. its still gunna be a backroll.
tantrums can only go forwards. boat or kite it's exactly the same movement. a tantrum is a backflip in the direction of travel- you leave your front hand on the handle so it's not even possible to go backwards. think about the sequence: pop, turn 90 degrees to blind, and backflip.
if it were a backwards backflip you'd have to take your front hand off the handle, face the wake as you pop, and flip against the direction of travel.
