I think the best weight savings for the money would be to get a used or OEM closeout Fox Float or maybe an RVL. You want a slightly more laid back and comfy feel on the techy terrain? Get an F120. The saddle and crankset hoopla will be wasted money. Spending 200 to save 1/3lb will go unnoticed. The newer Float series (post-2005) is quite stiff and sturdy laterally / fore and aft. Nice trail fork. You'll sacrifice a little bit of butter, but if you haven't serviced the Van R in a while...it's probably suffering from a little bit of stiction. A new Float will be smoother than an unserviced '05 Vanilla R. (which is what year that one sorta appears to be)
