The ab you're talking about is the one near the end of E in the back vein (Cwm). Yes it's the one corin had one of his moments on. Yes it drops to G.
I did put a Batinox Resin Bolt into good rock in the floor as just something bomber to back up off. There are lots of expansion bolts in the wall above, not mine, most of these look quite satisfactory however. You've loads there to go off.
Further along inbye you go up the slope to DE, and shortly after you come to a new cowstail line dropping to a much shorter pitch to G. This is mine, it's a safer, easier way to get groups to G that the other pitch. Hence the extra long cowstail line, for punter-parking you see. The pitchhead there isn't finished, it's quite loose and awkward at the moment.
