I chopped a 60m half down to 40m after it was damaged near the end for glacier travel snow routes and ridges.
40m glacier rope.
Add gym classic 9 5mm x 40m non dry rope to compare.
The petzl rad system an complete kit designed specifically for crevasse rescue uses very low stretch 6mm static rope.
Semi static ropes are designed for caving canyoning rope ascent or hauling as well as for bolting a route.
I agree with the greater versatility of a 60m rope used for glacier rock ice not arguing against that.
Mammut makes a 6mm dry treated glacier cord also a static rope designed for crevasse rescue.

This rope has a middle mark and comes with a nice storage bag which can be used for a clean toss when you need to rappel.
40m seems like enough rope for most glacier travel scenarios with 2 3 person rope team.
Prior to that the 60m joker was used for everything.
I don t foresee needing long rope for belays or raps because i m not looking to do big crazy steep sections.
Would it be dumb to roll out with only 40m.
Particularly applicable for short belays when partners need to be within visible range and maybe occasionally simul climbing with a running belay.
Where falls are generally low impact and forces generated are well under the rated kilo newtons.
I do have a 60m half and a 60m joker though if the route calls for it.
Don t care about it as a climbing rope because i have a non treated workhorse for pure rock.
Gym classic 9 5mm x 40m non dry rope.
I see this rope being a real plus on glacier traverses and steep snow and ice up to 50 deg.
I m more than happy using a single half in such scenarios and the extra length of a 60m just isn t needed.
They have the advantage of having low stretch and are very resistant to abrasion yet remain flexible and lightweight.
