Petzl is also launching an new 8mm caving rope for " expert caving activities". So I presume only for exploring/expedtions.https://www.petzl.com/NL/en/Sport/New/SEGMENT-8-0-mm#.WJwsijiQyM8Dagobert
I note they call it an accessory cord.
this document (not by petzl) shows that to meet EN1891 (static rope) the diameter must be at least 8.5mm. so a true 8mm cord would not ever meet the standard and couldnt be used with the stop without going against the manufacturers written instructionhttp://www.mytendon.com/file/340/Manual_horolezeckych_a_pracovnich_lan.pdf
Ropes of 8 mm diameterFor experts, the SIMPLE may also be used withropes of 8 mm in diameter.Attention: ropes of 8 to 9 mm diameterWarning, the braking effect is strongly reduced.Additional braking systems must always beused. Check that the rope is compatible with themethod of use required.
I dropped a 200m freehanging pitch in france on 8mm. I used a simple and a Raumer handy. No problems. Sent from my iPhone using Tapatalk
You weigh piss all. You wouldn't see me doing a 200m drop on 8mm! I am fast enough on new, wet 10mm rope in Rowten using a Stop.
In contrast, Cordes Courant rope seems far faster - very noticeable switching directly from one to another.
You can (in theory, never tried it) put an Italian hitch on your braking krab
Yes, although might this not twist the rope? Could be troublesome if there is a rebelay below stopping the twists from dropping off the end.
True - you could always do a 'super munter' instead (which doesn't twist the rope), then you would be pretty much guaranteed not to go anywhere

I am fast enough on new, wet 10mm rope in Rowten using a Stop.You can easily slow yourself using the "S + O" technique, as shown in . If it's still too fast (unlikely), you can abseil on a half-lock.I believe the Stop is rated for 9+ mm because, on thinner ropes, the autolock action is ineffective.
This S+0 is certainly interesting but is it safe to create this rope-to-rope rubbing? I wonder whether your won't increase your chances of melting it on a longer drop.
