In reply to Misha:
I'd agree, if I can link pitches, I will. I have 70m half ropes that I'll take to some crags, like high tor, or baggy point, knowing there's some 60m pitches.
I like climbing, though setting up and belaying is fun, it's not as good as getting in the zone and climbing.
Falling, though possible, isn't a frequent event when linking pitches. Not many will push their grade and double up the pitches too, that'd be daft and optomistic.
Distance fallen does get bigger, I know this, and have fallen lots of meters when not that far above the gear, if the fall out is safe, no problem. I can think of many routes with single pitches which offer a pin ball descent too.
Often, the pitches aren't long anyway, so running 2 together isn't a biggie
Anyway, rambled on. +1 for running pitches together.
