I have two dry-treated 70m Mammut Infinity ropes. Both these ropes are a few years old at this point, but have only seen maybe a dozen or so pitches each and have plenty of life in them. 

I worked in shops for a few years and fell victim to buying way more shit than I actually need. Nothing sketchy about these ropes, I just prefer thinner cords these days.

Anyways thinking $100 each. Local pickup is probably best. I'm in Golden.
