In reply to sea_lene:
Yeah, it's a decent sized ledge. You might have a bit more swing potential on the first pitch than you would with one second on two ropes, but not (IIRC, YMMV, usual disclaimers apply) to a dangerous extent.
Speaking of Buckbarrow, we went there the other weekend and did the guidebook approach up the scree at the front. But looking in the ever faithful Wainwright, it looks like there's a slightly longer but much nicer path that starts up Gill Beck and neatly drops you at the bottom of the upper tier. Is there a reason that people don't use that as an approach instead?
