> DMM, Beal and Mammut all do them fatter than 10mm, DMMs workhorse rope is 10.5, though they do say its for instructors and walls.
I think that is the point - their handling is really not very good which is why they are used at walls etc. If you are using it to work routes in sustained long sessions, then a workhorse is what you need, but I would still go for a 10mm max.
> My 10.2 Beal works fine with a grigri, though it didn't last very long.
Gri-gri 1 or 2 - big difference.
> I suppose I am looking for 10mm or above, I basically don't want a thin rope as I already own a 9.2mm that only gets used when needed. Which is lucky given that is worn through on a 3 week trip.
Is that a thin 9.2mm single rope of half rope? Again, big difference.
The triple-rated ropes allow you to by one rope to suit all needs but those by necessity need to be quite thin 8.9mm to 9.5mm ish.
