Hi Tim
1990 Rockfax , on the LCW, has A career with prospects,Extra over, Bolt revolt, Brain dead dave and Hyperactive housewife as all climbed to a bolt belay on an assortments of wires pegs and threads but no bolt runners.
All the other routes have at least one bolt runner.
The other " traditional " way of getting up Malham , of course, used to be aiding up.
Very popular in the 70's, even to the point of wearing out the bolt hangers
Most aid routes used a lot of bolts, including a lot of strange homemade thingies.
