Rob is perhaps referring to a 30 foot or so fall I took off that pitch, BITD before cams. Worked hard to get opposed nuts at the lip, nothing else available after that; perhaps small cams have changed that part. It was late winter or early spring and there was a thin stream of ice water running down the route after I cleared the ceiling. The ice water progressively numbed my hands, which went from being ok to worthless for gripping very suddenly.
The fall was all air. I didn't fancy another bout with the ice water and bailed. Came back in a few weeks and did it when it was warmer and drier.
