So, I was pretty happy with my Rockshox Dart 2 forks until recently, when I've noticed that I'm being rattled around quite a bit. Will a better fork make much of a difference, or in my old age (40 in January), is it time to get a dual suspension or full suspension? I've also heard that 29ers take a lot of the bounce out since they kind of just roll over things. I have been riding in areas with lots of roots and rough spots on the trails, and I'm being bounced around quite a bit...wondering how much of a difference a new fork, FS, DS, or 29er will make.
