I have an older Spec. Hardrock that I keep around for tooling around the hood and for friends without bikes. It's a 19" with a 100mm Psylo. The Psylo is way too soft, there isn't any compression adj. left, and can't find stiffer springs any where. I was thinking of going to a Reba RL 120mm. My question is...will the different axle to crown measurements between the two forks change the frame stance that much?
