In reply to Richardlake:
I've done it on 50m and 60m ropes. You can just about make the tree belay on 50m ropes, but have to belay from there. ( a few meters back from the lip of the wall). 60m ropes at least allow you to sit on the edge and saviour the view down. And yes, the jim grim finish is defo the way to go, no harder than the rest of the route. Jim grim is a good route as well, quite a bit harder with much less gear i seem to recall.
