I'm being somewhat serious.
Look at this group of highly tuned athletes:

Here are the bikes they're riding from left to right:
1. Used Specialized Stumpjumper FSR (full suspension) - I'm guessing he weighs about 170
2. Specialized Stumpjumper hardtail with Fox shock - I weigh 185
3. Trek 4500 ($500 bike or so) with some rock shock crap on it - He claims 230.
4. Specialized Hard Rock ($500 bike or so) with some rock shock crap on it - He probably is a true 230.
Neither of the pudgy guys are bitching about the shocks bottoming out, exploding or tossing them into the woods. They're riding/racing single track with rocks, drop offs (24" or less generally), creek crossings, log crossings etc...
I'd say find a bike that fits and keep your weight back over the jumps. You'll be fine.
