In reply to Psych:
If you're going single pitch redpointing, falling a lot as you say, then don't bother with anything fancy. Get a big fat, long if you're doing routes over 30m, non-treated rope.
If you're going to be doing something more adventurous, then I'd still say long (70m), but go for 9.5mm or less, dry treatment is useful. I too like the mammuts, I have an 70m 8.9mm infinity and its been great, but I'd probably go for 9+ next time as the granite here chews it up too quick.
If I were buying a rope now, I probably wouldn't consider one that wasn't rated as both a half and a single, and I'd want the mammut duodess pattern where the stitch changes at the halfway point.
I think anyone that buys a 50 these days is a bit daft, as a 60 has so much more flexibility; as well as long pitches and 30m sport, you can fold it in half and use it as a pair for 99% of grit routes, MUCH cheaper than wearing out 2 ropes. That's also why its useful if its dual rated.
