selkirk Posted July 4, 2008 Share Posted July 4, 2008 I'm interested in getting a tag line to use for rappelling. Any suggestions on diameter???? 7mm or 8mm?? TIA Quote Link to comment Share on other sites More sharing options...
Braydon Posted July 4, 2008 Share Posted July 4, 2008 I use 6mm...hold on! Steve House used used a 5mm on the Rupal face. I guess it depends on how much weight you want to carry. Quote Link to comment Share on other sites More sharing options...
NoahT Posted July 4, 2008 Share Posted July 4, 2008 He used 5mm tech cord--high strength, low stretch--I used 5mm accessory cord last season and found it great when dry, total bullshit when wet...way to STREEETCHY and thin to really be able to pull your lead rope without lots of monkeying around. I'm bumping it up to 6mm now, so we'll see... Quote Link to comment Share on other sites More sharing options...

TIA if you are really thinking about this size you may just as well go with 7.5mm twins and thus reduce the total rope weight significantly.

TimL Posted July 4, 2008 Share Posted July 4, 2008 (edited) Depends the length and diameter of your ropes and actual practicality of what and where you are going to use it. I recently started a thread about this very subject. I fould out, at least for me, that a thin line isn't an advantage. I have a 70 meter 9.4 lead rope and I was thinking about matching that with a 6 or 7mm rap line. I also have double 8mm 60's that I normaly use when alpine climbing. It was obvious to me that the 70 meter (9.4 +6mm) and the twin 8mm 60 system weighed about the same. The only advantage was 10 meters which I find is not that much of an advantage. The disadvantage was screwing around with a small line when your rapping and tired and carring it in your pack. I think if you really want to cut weight and then go with a twin 7.5 system.

tradhead Posted July 4, 2008 Share Posted July 4, 2008 Anyone have experience using 7.5mm twins for alpine rock? I've heard bad things about rope life if they're used for anything other than ice climbing, but haven't tried them myself. Quote Link to comment Share on other sites More sharing options...
Moof Posted July 5, 2008 Share Posted July 5, 2008 I'm pretty happy with my 7mm static as a second rap line, and as a tag line for aid stuff. YMMV. FYI, even 7mm can be a pain in the arse in the wind, or if there are a lot of chicken heads (red rocks), so adjust accordingly. Quote Link to comment Share on other sites More sharing options...
