[tag=276218]@ev.grover[/tag] is giving great advice here, just wanted to expand on this a little bc I built the jump he was hitting (and hit it with him of course) so people can get a better idea of the jump. I'll just stick to pow jump advice bc I've never hit a double on a park jump, all I can say or certain is crashing in pow hurts less.

Its probably bigger than it looks in those videos, maybe 10-12ft tall bottom to lip, then it steps up 2ft or so to the top of the landing, and to the sweet spot in the landing was probably close to a true table. It was tricky to get the airtime to dub without landing in that cat track you see in the last video, so we built it very steep, steeper than I've done before for doubles, maybe 45-50 degrees which straight up looks near vertical when when you hit it. We spent a TON of time making sure the curve was super consistent, its basically a constant radius from the bottom to the lip, this helps you get a nice controlled set. Definitely kicky, but not so much that you would get bucked or struggle to control your set.

The landing started out amazing but got more and more packed as we sessioned it, but because the jump set you more up than out, a nice steep landing, and had very little step down, crashing on it was never really bad at all. I'd definitely recommend a jump like this bc it's likely you will bomb the shit out of your landing.
I think most people need more air time than they think to land their first double. My rule of thumb is a jump big enough that you have to intentionally set very slow to float a single backflip. If your test hit is a laid out backy and you over rotate and land on your back, its perfect.
Hope this helps!
