In reply to Harry Cook:
In order to make it more likely that Mrs Wilko and I can get to the start of the odd high crag route with enough energy left to do the route I recently cut down two 50m half ropes to 30m. The first route we tackled was Gillercombe Buttress. There weren't any real problems, but I took the precaution of using an old guidebook. The current guidebook gives 6 pitches, of which three are 40m. The 1968 guidebook gives 9 pitches, the longest of which is 60 feet.
