Rope pigtailing

I carefully uncoiled it following directions, and it was mostly fine. A bit kinky at first, but straightened out after a couple of raps.This is not the case anymore for mammut ropes. My roommate just got a mammut rope and it was not pre-flaked. |

^^^. Likely due to the fact that mammut ropes are being made by a different rope manufacturer now. |

The instructions that come with mammut ropes is not very good so just watch one of the numerous videos on youtube. eli poss wrote: This is not the case anymore for mammut ropes.

Mammut ropes are good to go I do not know how long Mammut has been doing this for - at least a few years... Likewise, all of the current Petzl ropes (made by Edelrid, then shipped to Petzl where they undergo a "treatment" are put in a machine that coils them in a way that also makes them good to go,with no special uncoiling procedure is necessary. Petzl communicates this on their packaging. Petzl ropes are good to go |

Chances are you're twisting the rope 1/8 to 1/4 turn every time you take in rope through your belay device. |

thanks for all the feedback. |

Oh, the internet rumor mill... |

Yo man, quick fix, too: |

Thanks, Kurt. |

I've watched this happen a fair number of times. |
|
the time I noticed it the most was doing a traverse between routes for a link-up. im guessing I need to work on my extensions more to reduce rope drag to lower pigtailing. |

In my experience, every "ready to use" pre-flaked ropes still have some subtle twists in them. I always reflake them for at least couple of times to avoid cluster-effs during climbing. I always end up effing up the factory butterfly anyway while taking out of the package. |

Just an experiential update ... kinda lengthy ...
In general, I think the above indicates that the rap/belay devices themselves were not introducing pigtails.
As the rope was pulled through for the second to follow on top-rope, significant numbers of pigtails developed on the second's end. Note that the rope-side biner at the last draw was probably against the rock as the leader was lowered as well as when the excess rope was pulled through. Likely, the same condition existed at the top anchor. My intuition is that the rope-side biner(s) on the last bolt and/or at the anchor was/were held out of how they would naturally orient to the rope action either during lower and / or when pulling through the excess rope. I suspect this "un-natural" biner orientation caused the rope to slightly spiral through a rope-side biner(s) which promoted twisting. Edit to add: I am less suspicious of it being the lowering that introduced the pigtails because we did not notice any pigtail-ing during lowering. This leads me to think that a loaded belay device while lowering prevents/minimizes the ability of twists to pass through to the free end of the rope. |

Anyone touch on this? As belayer or rappeller, you can feel the rope twist in your break-hand. Resist those twists and stuff right into your device. |

One of my climbing partners has a way of introducing twists in the rope when he belays. We went out recently so I could get a belay and finish a (three-year!) project before the first snow (send!). We used a rope he’d never touched before. I’ve used the rope many times, and on that particular route, and never had any twists. I took three burns to send the route and we had twists after the first burn. He uses an ordinary ATC (not Guide). Does the same to gym ropes. |

If you can feel the rope beginning to twist, consciously twist it slightly the other way as you pull in slack, or switch belay hands and see what happens. I was putting lots of twist in the rope when I started, until I became aware of this slight , yet cumulative twisting. |

thanks for the in-depth Bill. |
