In reply to Owen W-G:
> 1. I've heard 50m ropes won't allow you to do it in one massive pitch. My mate has 55m ropes, will they do?
50m ropes will do, but you won't have enough to get to the tree, which is far back, to belay. You'd be better off leaving another rope at the top for the belay.
> 2. Is there an ab station at the top? If my mate and I both want to lead it same day, is the ab down to strip gear definitely on?
No there isn't. See above.
Dunno sorry. The first crux of Darius is well protected, the top crux, above the old bolt, is bold.
