    I recently purchased a 100 meter (328ft) rope and am wondering what everyone is using for pull cords on 300ft ropes?

    Thanks, I figured that 6 or 7mm accessory cord wouldn't make the pull easy over 200ft but I was holding out hope that someone uses a thin light cord.

    One of the high tenacity cords from Sterling. I like the 5.4mm V-TX

    But might cost more than you rope :cry:

    A couple of 200s tied together. Maybe a 200 and a 100, depending.

    You don't want to wear out your 300' rope using it on shorter drops anyway, not to mention the hassle of deploying a big rope for minor drops so any canyon that has a long drop in it you'll have other working ropes with you to use as the pull for the 300'. The one exception is if you fiddle the big drop in which case you'll want as light of a pull cord as you can find. Most use a 3mm dyneema pull cord for fiddling long drops.

    +1 for the fiddle and a 3mm dyneema cord

    In these discussions, it can be helpful to distinguish between:
    • pull cord, a cord tied to the end of a rope, used for pulling the rope through a fixed anchor
    • release cord, a cord tied to a toggle or other release mechanism, used to release a retrievable anchor system (e.g. toggled rope, Water anchor, etc.)
    Toggle = Fiddlestick / Smooth Operator / etc.

    Most folks use pull cords of 6 mm or greater diameter, whereas a lightweight dyneema release cord can be much smaller in diameter (1/8" Samson Amsteel-Blue is commonly used). Note: this pull cord/release cord nomenclature is not in common usage, but here's hoping it (or something better) eventually catches on.

    Some quick thoughts here on multi-purpose and how the correct answer is situationally dependent. I do a lot of climbing (multi pitch trad, ice, alpine, some single pitch stuff) some some thoughts I have around rope selection are anchor building. When I'm climbing, not canyoning, I don't plan on leaving my own gear behind for anchors. I generally expect, bolts, tat, or something but I do bring stuff to leave behind a few. Somethings that's cutting the end of my pull cord (btw pull cords are not common in the climbing community though a few people do prefer a lead line and pull line vs. halfs (spelled weird) vs doubles). Sometimes though I make sure to bring leaver biners/rap rings and my own tat if I know the route isn't done frequently.

    Back to canyoning some considerations:
    After it gets stuck how much is left and how would/could you finish without it?
    That brings up risk acceptance. IF you know you can't finish if it gets stuck, you didn't bring a backup, and you told people where you are going I assumed you were prepared to wait out rescue.
    If you start getting desperate can you start cutting and leaving it as anchor material?
    multipurpose: what other uses can you do with whatever you bringing?
    Weight generally inversely proportional speed
    weight generally proportional to robustness multi-use
    How familiar are you with the techniques. I don't know Austin (OP) but a lot of people talked about 3mm with a fiddlestick/smooth operator, what if Austin doesn't know those techniques? That's not a useful suggestion for his knowledge base. He can expand his knowledge base or wait for a more appropriate answer.

    possible answers
    bring extra shorter ropes you will tie together
    bring another equal length rope
    bring something super skinny (never to be used as an anchor or to be rapped on)
    bring something skinny you can cut an leave as anchor material or rap on in emergencies. For example, I know how to rap on 6mm cord and have done it several times so a good tag line for me is about that diameter. If the second isn't climbing with a bag we can still throw it in a potshot and clip it to our harnesses.

    So my approach is to have a wide knowledge base, do my research on the canyon (if it's an exploratory or very little beta I might be going the heavyweight option), lots of gear tools and tricks, and have a plan. Sorry that's not a clear cut answer.
