Investing in good protection wouldn't hurt either. Ass pads and spine protection if you so feel inclined. I'm thinking of getting one for even general riding. POC makes some really light weight ones.
All that aside, you should still definitely take it easy. Don't just get all trigger happy. I only pull out the "EFF it" method after I'm comfortable on the jump for new grabs and stuff. For example, I started out doing indies on a jump and kept sketching about a suitcase grab (in my avatar, that very day). Then I said to myself, "Eff it, I can do indies and land it fine, might as well go for the suitcase" and bam landed the first try. I did bail the next two though lol.
I suggest just hopping over the jump first so you can get the scope of the jump. Just progressively go bigger and bigger until you feel you have the speed and distance down.
