Replying to Bottoming out on my 7's and 9's

Sup Guys,

So lately, I've been trying to not have any fear and just hit everything huge, and I just recently started throwing 7's and 9's. But the only way I can get around is to really get a lot of speed and get in the air for a long time. Which means that at my park.. where the biggest feature is like a 60ft kicker, I end up landing in the flat. That is fine for 7's but not for 9's as I have landed on my tails a lot and have had 2 concussions (sp?) in the last week, any way to speed up my rotations on the bigger spins or a way to stomp it switch in the flat? Thanks...
