JoshK Posted July 10, 2003 Posted July 10, 2003 I know this has been covered before. I don't care, cause I can't find it. I'm gonna buy some cord for an alpine haul/rap line. Trying to decide between 6mm, 7mm, or 8mm. 6mm seems scary, I can't imagine rapping on that. 8mm seems nearly as thick as a normal rope, so maybe too heavy, thus I was thinking 7mm. Any body have any advice? Quote
erik Posted July 10, 2003 Posted July 10, 2003 there are few routes in the casecades that i can think you would need a haul line for. or prolly even two ropes.(and i know i am prolly wrong, so feel free to help me out!) but i would go with the 7mm and get as tech as you can afford. vectron is a good start. how do you plan to rap with it?

iain Posted July 10, 2003 Posted July 10, 2003 maybe he means do you plan to bend it onto your normal climbing rope, or rap with it as a single line... Quote
Paco Posted July 10, 2003 Posted July 10, 2003 FWIW I think Dean Potter used 100M of 6 mm line for his solo escapades in Patagonia. You can read about it in AAJ 2002. Getting off of those climbs in Patagonia require many raps so if 6mm if good enough for that, I would say go with 6mm. If 6mm scares you too much, use 7mm, but 8mm is definitely overkill. Quote
erik Posted July 10, 2003 Posted July 10, 2003 iain hit it on the head. are you planning on double rope rapping with it or using it as your pull line for single rope raps? Quote
catbirdseat Posted July 10, 2003 Posted July 10, 2003 I really think he intends to use it bent onto his regular climbing rope for double rope rappels, or for a haul line. Where can you buy 7 mm Vectran? Quote

I would like it to be as versitile as possible. When used with a normal climbing rope, I think using it as a pull line would be easiest since rapping with two ropes of vastly different sizes can be akward. I would also like to use it for single rope raps where i wouldn't have a climbing rope with me...such as soloing where I know rapping will be much easier than downclimbing. Quote
erik Posted July 10, 2003 Posted July 10, 2003 I WOULDNT SINGLE RAP OFF ANYTHING SMALLER THEN 7MM AND EVEN THAT I WOULD BE SUSPECT. CBS, THE STORE. Quote
Figger_Eight Posted July 10, 2003 Posted July 10, 2003 I second that. I don't think I'd worry about it breaking, just getting cut on a sharp edge or something. Quote
Stephen_Ramsey Posted July 10, 2003 Posted July 10, 2003 I've rapped on 6mm perlon cord before, with my Reverso. The sheath on the cord stretched in a disconcerting manner. 6mm cord is also really easy to accidentally cut over a sharp rock, or with crampons. I'm going to get 50m of 7mm cord instead, and leave the 6mm cord for prussik loops, cordalette and such. Just my opinion. Quote
