I use the
@Cain method for climbing with the WE Stepps. Going up I'm always tethered and I can just reverse the process coming down. No need to fish around in the dark with a foot for the aider.
If you haven't seen it a link to the Cain method is below. It is pretty simple. I don't kick off the tree like Cain I just push away with my foot and with a tight tether you swing right up to where you can get your free foot on the next stepp. Only downside is having to tie stepps above your head but that gets pretty easy too with practice.
FULL DISCLOSURE: I actually take a long enough rope with me for a tether that I most often rappel down and remove the stepps as I go.
