In reply to Barryt128:
It's only my opinion but rather than a single rope id get two doubles. It may cost more but if, as you say, you're going to do most of your climbing in winter it makes more sense.
I made the mistake of getting a single 50m when I started a few years ago and I prefer winter climbing. It must have made six outings before I bought doubles. False economy to shell out for a single, then doubles months later. Just by doubles to start with!
Especially in winter I'd get a pair of 60s.
