Judging by your avatar, it looks like you have come from a surfing background riding goofy stance all of ur surfing life, so attempting any jumps/tricks riding in the goofy direction (right foot forward) will naturally feel easier. The key is practice and persistence trying to do the same tricks riding the opposite direction. Next time u go out spend the
whole session trying to do your jumps natural stance, it will eventually click. When learning new tricks I always make sure i can complete the same trick going in both directions before attempting to learn a new one and yes it is always easier one way than the other so practice more on ur weaker side.
On ur other note, wait till u start looping the kite

BIG whooshes yeeeew!
