Replying to Falling in the Park

Okay, so I was thinking about trying some new tricks in the park, on some normal size jumps (15-25 feet, South Park at Mammoth for those of you who know). I am currently clearing every jump in the line, and doing mute's, shifty japan's, etc. and I was thinking of trying a 360 and/or a backflip. The one thing I was worried about is how mad people seem to get when someone falls on one of the jumps, that and there the next person would land on me before they knew I had fallen. Oh ya, one last thing, I have had 6 major concussions in my life and don't want to get tooo many more, so avoiding landing on my head would be a good thing. Opinions, suggestions, flaming, etc. welcome.
