I used to concentrate on getting the forks right because that's what I felt the most plus you see them work. Then I finally broke down and had my shock revalved and sprung properly. The difference it made was 2X what any fork mods have ever done. With the shock set up as close to perfect as possible it makes the forks work better. I can't say the opposite is true and I've been there. For the type of riding I do the shock is slightly more important than the fork.
