Since getting a 29er hardtail for XC, I've been converting my 05 Enduro Expert specifically for downhill. I've done all I can think of except for the suspension. Right now, it's a Fox DHX 5.0 Air on the back and a Talas 36 Air on the front. I'm about 200lbs and not really sure how far I could push this setup with the current suspension. Do you think switching out to a coil suspension would be necessary? I probably wouldn't jump off anything over 3 to 4 feet, don't know if the frame would be able to take it.
