Haha, I think I'm getting jaded by all the weight-weenies on this forum, so I initially suggested the air shock. I prefer coil too, especially for a bike like the Heckler; although, the air units - - especially with the advent of the RP3s - - have come a long way.
I'd steer clear of the DHX5. I missed that generation myself, but I read way too many people having fiddly issues with them and couldn't wait for the RC4 to come out. I have an RC4 and it is an awesome shock. If you run across a deal on a Rocco WC, it's worth a look. Lesser Roccos had issues I believe but the WC I had performed flawlessly.
