I have a Komodo and like it, but not as a dirt jumper. Too slack, too much travel up front, though to be fair, I have a pretty big fork on there, and it would be significantly steeper and stiffer with the Marzocchi DJ that comes with the Komodo II. I also have a single-speed rigid DJ, which is great as a dirt jumper, but crap as a trail bike. I'm thinking there are a couple possibilities here:
1) Komodo with a DJ, Argyle, or 831. That's a burly frame, and a short fork will make it a better jumper.
2) A geared 26" DJ. The geometry isn't ideal for trail riding, but it will make a great jumper, and is still passable as a trail bike.
3) Something like this: http://www.leelikesbikes.com/captain-america.html I haven't ridden a bike like this, and the frame won't be as burly as either of the above. That said, I've taken lessons from this guy, and he's a badass. He's abusing that bike, and he seems to like it. Lots of stuff on his website about it...search for "Captain America" and he has lots of info as to how it performs both on the trail, the pump track, and even on a BMX track. It looks to be a little of a jack of all trades, master of none kind of bike, but it's worth a look.
4) If your focus is downhill or freeride, you want a downhill or freeride bike. I've got nothing. Lots of guys on here who can help you with that though.
