I've taken mine off of five foot jumps with a 10 foot horizontal flat. Wasn't a problem really. Haven't done anything bigger yet as the conditions have been pretty shitty so far. Like I mentioned in my original post, it's a bit shaky on landings. It doesn't like to bite in as much as I would like it to...it's hard to describe other than to just say it's squirmy.
That being said though, it's still alright, but if you wanted to hit huge kickers, I'd go with a different board.
