Lava, to be precise. Haven't even tried anything else, it works fine/great.
I do wonder, though, from the original pictures posted, what the over-the-back tether is for - slack tending? Sorry if this has been addressed, just started reading this thread today so may be a bit behind.
Is that how all of you other RW users are tending slack? For me, ascent is not quite as easy as it used to be, pre-RW, when I just used a long prussik loop, croll and pantin. Doesn't seem like I can use the croll along with this hitchclimber setup, and I don't get the long up-strides I used to.
Now I just stand up and pull the RW/hitchclimber mass up, then stand up again and repeat.
Does this make much sense? I didn't get much sleep last night, but need a little help on my setup. I love this tool, just haven't gotten back to the speed I used to have on ascent. Seems like the time I've made up in not switching systems at the top has been swapped out for smaller steps up.
