Hmm, yes, no waterfalls when I was there.
It seemed to me to be a bit more technical than other grade 1 scrambles I've done (which isn't many) insofar as I actually needed to think about where to put my hands and feet a lot more - it helped when someone suggested that the deepest part of the trough might not always be the easiest route. But I didn't really notice much exposure, which is particularly nice given that you can show people a picture of Pavey Ark and point out your line of ascent across the huge sheer precipice and get far more respect than you deserve...
