You don't know if he's doing it right. And snapping your tail on a straight air is jumping 101. Unless you are watching too many snowboard addiction videos.
If you simply ride off a jump with a little hop at the lip that doesn't mean you are going to get any pop out of your tail. If you never learn to do that via timing and board control you will never have a straight air with any boost.
Well from his description of what he's doing it sounds like he's doing it right:
"When going off a jump, I flex my knees at the base, and extend my knees and then do a small, controlled jump at the lip, and then suck my knees up? I feel like my form is overall stable, but I am just not getting nearly as much air as my friends."
If you want to snap your tail off the lip on a straight air you can I suppose, it's not something I ever do or ever needed to do, especially not as the jumps get bigger and stability becomes more important than boosting up for no reason when I'm already landing in the sweet spot of a jump.
I suppose it's something you could do on small jumps, but I have no idea why you'd want to be doing this as you move to bigger jumps.
It was my impression that his question was "basically" why do some guys get way more pop off the same kicker at the same speed than others (something you can see everyday in the park) its because they are snapping the tail on the jump. Im the guy who used the word ollie because in my age group (jumping with Jussi
everybody knew what snapping your tail or ollieing off a jump meant. And most people still do. No one thinks this equates to a flat ground ollie, simply loading the tail on a straight air the same way.
This idea of not teaching beginners this is something real new in the last five years and for different reasons .
I think we went into this with different assumptions on what he was asking. From his description it seemed to me like he said his friend was just jumping really hard off a jump and getting more pop, but was also unstable and he wanted to know if he should be doing that too or if his current pop technique was wrong.
I'm not really there on the whole snapping tail on a straight air thing, but I suppose if some people want to do that off jumps they can *shrug*, seems odd to me to be increasing your instability vs just popping though.
