I am looking for a rear shock upgrade for my GF's jamis dakar sport.
She is 130 lbs and has been riding off road for a couple of years. The bike has an X-Fusion Glyde R. We are looking for something more plush and responsive but not an expensive hi tech race shock.

I have looked at Fox vanilla R, rock shock bar 2.1. Would these be a good upgrade? Any other suggestions would be appreciated.
