In reply to kingborris:
You would probably be OK at Subluminal, if you used long extenders to keep the rope fairly in line.
At most of the other venues, I think you would experience serious rope drag. I have only ever climbed at Swanage with doubles and using reasonably long extenders and slings where necessary. Even then, I have occasionally had some pretty bad rope drag over the top on the steep mud and grass slopes before any belay is possible.
Edit; I would just add that, like sea cliffs such as Gogarth, climbing at Swanage is pretty intimidating and steep and pumpy. It is the last place you want to be pumped a bit scared and fighting rope drag shouting down to your belayer "GIVE ME SOME F*****g SLACK! whist the waves are crashing and the wind is blowing and your belayer cannot hear anything......
Invest in a couple of 60m half ropes and have a much more enjoyable, stress free time.
Cheers, Rich.
