i think 60m 8-8.5mm are the go, i have never regreted there longer length as it means you can link pitches and make longer raps,
We managed to chop one of our 60's in NZ last year and as the climbing shop in Wanaka didnt have a 60m 8mm we had to climb the rest of the trip with one 48m rope and one 60m rope, totally sucked and its a recipe for confusion and disaster |
