Hey folks, going back through some older posts here it seems that a half rope is a favored option for glacier travel. There seem to be some differing opinions of whether it’s better to go lighter and thinner (in the range 7 - 8mm), or slightly thicker (8.5-9mm). Obviously a thinner rope reduces weight but my understanding is that it makes rescue and belay tasks more difficult.
I’m looking at ropes like the Black Diamond Dry 7.9 (39 g/m) and 8.5 (46 g/m) in a 60m length so it’s possible to use for rappelling too. Obviously the 7.9 is a decent weight saving in that length, but not sure if it’s worth the trade-off for sacrificing some functionality in rescue scenarios etc.
Any thoughts (or suggestions of other ropes I should be looking at) are welcome.
