I second the cane creek cloud nine. It makes you feel like you have a completely new bike.
If you call CC, they can custom build you one based on the frame. For the HG full suspensions, it is a 5.5 eye to eye and I believe a 1.25 inch stroke for about 3-3.5 inches of travel. Adjustability on the Cloud Nine is great. If you want more or less travel they could probably build it to your spec.
