I at first thought that the psylo was a much better fork. Since the original comparrison happened, I had some major seat time with it, and it just did not track as well as the Z1 did in really tight conditions. The front feels more planted with the Z1. Plus I did not have these mechanical nightmares with the Z1 it was set it and forget it. Had it back for all of two hours and it broke again. Not one fork problem all year with the Z1. When I get back up to NH, the damn psylo is going to be removed. I had the fork that I was happy with, I never knew it and got lost in adjustable travel.
