nice ones...getting there, no?
Boardoff: try to get more power...higher, longer, then you can stretch all the way out and hold the positions...will look awesome!
Frontroll: it is actually a Front 360. You use the kite to jump, that makes it fronts or backs.
If you keep the kite at a position without using it to jump, it will be a roll.
But backroll boardoff is possible, see my DVD
