In reply to chrisholl24:
> 1. the pros & cons of half rope vs single rope? When can /can't use etc...
ok here goes,
advantages of two half ropes over one full rope:
*)If thw route includes a traverse the leader can be protected better and more easially with two half ropes.
*)rope drag can be reduce with two half ropes (all the gear is not clipped on one rope)
*) if you need to retreat from a route, you can do less abseils and so retreat faster using half ropes.
*)If two people are building a rack between two people it is less hassel and easier if each person buys one half rope each as most climber have half ropes (I have a half and a full rope)
*)two half ropes can be carried by two people so 1 person doesn't have to carry all the weight
Advantages of one full rope over two half ropes:
*)On shorter route (single pitch) which don't include a travrese it's easier and less hassel to use one full rope.
*)over all weight one full rope is lighter than two half ropes (especially if they get wet)
*)Pro rata one full rope is cheaper than one full rope
> 2. when/if OK to use on scottish II & III in winter? Any issues/ limitations to be beware of?
regarding scotish II/III routes I think it's subjective depending on each route.
for winter there is an issue with ropes freezing paying the extra and buy dry ropes would be a good idea.
Personally I have a 50 meter 8.5mm dry half rope (dry treated) and I have a 60 meter 10.5dry full rope.
I'm sure I've missed things here and someone will point out any errors I have made.
