So... we're getting a little more organised about getting topos completed. We've got a good little system going and they will usually be completed in next to no time. Take for example this one...

Taff's Well Pinnacle

I didn't take the photo and have never been to the crag but was able to complete the topo in about 45 mins. (Photo from Rob Mc. and info from Alan R.)
