I've got some Works dual rates on the Blaster right now and I believe it's valved for a 165lb rider....I'm about 190 right now so that's an issue. At any rate would adding some nitrogen to the shock aid in the nosedive I am getting? It's been nosediving pretty severely. Doesn't seem all too bad except under braking, so while revalving would be the best route, it's rather costly and I am probably selling the Blaster around the end of the year, so would adding some nitrogen help alleviate the issue any? :-/
