It will take 5 or 6 climbs to get a “system” dialed in. Do the same thing climbing and descending.
And probably more sits than that to fine tune your bridge , tether, straps on the saddle etc.
They can be somewhat comfy once dialed in. What ever your foot platform is, you will most likely need some hard soled boots if your platform does not have angled foot rest. My experience has only been with one saddle model.
