First off can ascenders be used on dynamic ropes? I feel like i heard somewhere that ascenders can hurt dynamic ropes but I can't find anything that says that. Something about sheeth slippage is what I seem to remember. If they can't be used on dynamic rope then the rest of this question is pointless.
I have a climbing partner that is just learning to climb but would like to try a multipitch with me. He has his eye on a climb thats a little harder than he can climb though. Its 3 pitches. So I want to know if he gets to a part where he can't climb could he just jumar up the dynamic rope.
Obviously it needs to be safe. So I figure he could stop every say 5 or 10 feet and clip a figure eight on a bite to his harness. so he would always have his harness tied into the end of the rope but also a figure eight that would limit a fall if he needed. he would untie the previous intermediate figure eight when he tied another. I guess I took this idea I from an article I saw about toprope soloing.
So if this is just stupid let me know. I know it might be easier with a trail line but for now I have one rope.
Thanks
