Can you use two single ropes as half ropes?
|
Thinking of switching from single to half ropes. |
|
You're just describing a typical double rope setup. No issues with that, in fact lots of reasons to use that system in certain situations. |
|
Assuming you are using them as double ropes rather than twins (i.e., clipping only one rope to a given piece of gear), you are only actually falling on one rope. So no worries. |

All depends on how they are rated. Some manufacturers have put out ropes rated for both half use (alternate clipping ropes every other piece) and twin (clipping both ropes to every piece). |
|
Some half ropes such as the Mammut Genesis and Twilight are also rated as twin ropes, meaning that the impact force from a fall on both ropes at the same time won't exceed UIAA limits. |

I see that some have responded without seeing that you are asking about "experimenting" using two single ropes in double rope technique (clipping one rope per piece) - to see if you like it before buying. This is fine as long as you do not clip both ropes in one piece (twin rope technique). As you suspect, that would generate a higher impact. An option to buying two buying two half ropes in the future might be to get one half rope and one "thin" single rope. Use single rope technique or double rope technique as the situation requires. Kind of the best of both worlds if you only occasionally plan on using DRT. |

Thanks for all the replies. Just wanted to bounce it off a few people to see if I was overlooking something. Climb safe everyone !!!! |

They are easier to belay with, easier to lead with and easier to manage since they are basically treated as a singe. If I had a rope rated for halves and twins, I would use it as a twin most of the time. |

(Only one rope at a time clipped to any particular piece of gear, often used to reduce rope drag, also can reduce fall length while clipping.) The term "twin" rope is used for the case of clipping the two ropes together into gear, where the two ropes are clipped like a single rope. |
