Best trad/alpine/extendable draw
|
Yates sells a 1" tubular 24" rabbit runner, but that could be pretty bulky. |
|
Mad Rock makes some cheap, light, wire-gate biners. |

Do you happen to have a link to those tests? +1 to the BD Hoodwires, and looks like BD is coming out with an Oz hoodwire version: catalog.blackdiamondequipme… Available in May |

my 2 cents: |

They've done far more science on it than climbers have. UV damage degrades it relatively quickly. This is with tug lines, but still relevant as it deals with the fibers. down to 60% strength after replacement designed life (2 years). Not much of it has to do with shock loading or mechanical wear. samsonrope.com/site_files/R… It says right there in the sling card when purchased that you should be replacing it at least every three years. Any discoloration is a big no-no. |

In addition, that's with the improved SK75 blue fiber that hasn't made it to the climbing market. Think 2-4% more on your SK60 fibers used in climbing. |
|
interesting .... on one hand you have people on the intrawebs indicating that dyneema is worse than nylon for durability ... |
|
^ Thats why I like the blend that BlueWater Titan and Trango Ultratape use - also they have a higher than 22kn rating, so that as they loose strength over the years, at least its starting at a higher number than the skinny pure dyneema stuff. Seems like a good middle ground for material, size/weight, durability and all that crap. |
|
+2 on the camp express draws. |
|
Mammut Moses biners...almost full size and 27 grams and bigger than the nanos. Pair that with your favorite 8mm dyneema sling and its going to be super light. |

That DMM video has made me decide to have dedicated rope and pro/bolt carabiners. I am putting together some draws and like WC nitros for the rope end. I like the feel and open gate strength of the superlfys but find that orange garish. Any old silvers still around? Or other contenders? Or should I splurge on Heliums? |

Do you happen to have a link to those tests?I had the tests done on my rack of Mammut 8mm dyneema draws sending some of the slings to be tested at the end of each year over four years of use. They saw moderate use over that timeframe given I don't do a lot in winter up this way. By the end of the third year they were down to 9-11kn. At the end of the fourth year they were down to 7-10kn. On reaching them with the results, Mammut responded that they were designed as an ultralite alpine consumable to be used as such and not for year-in-year-out trad climbing. I wouldn't use them longer than two years myself. I've switched over to Metolius or Yates 11mmm slings and replace them every third year (but still miss the little Mammut sleeve over the joint). |

does anyone make nylon runners skinnier than 9/16? |

Tests have shown that 3 year old skinny slings break at half of their original strength. I don't want to buy a bunch of $10 slings every three years. If you need to leave gear behind at anchors or to bail, nylon is great. The skinnies still have their uses though. I still take two along as they can be nice for thin tie offs.They break at 1/2 the strength which is 10-12 KN , I may be wrong but You won't see any fall that generated that much force... I still have my 5 years old 10mm Wild Country Dynema runners ... but I am about to change them. |

Trango ultra tape starts at 25 kN anyways. |
