A lot of the problems on that wall had first ascents with a top rope and have often been climbed in that way. thunder is about the highest of the hard ones. i reckon a top rope aswell.
try the 5c one nearby - the cracvk that curves over. the wall is significantly higher than it looks in that bit as the ground drops. wouldnt like to fall from high up.
ps. i have backed off the 5c one every time for high and scary reasons.
Yeah I guess it's probably the most sensible way. Just a bit of a faff needing a rope and a belayer. Are there good anchors up there? I haven't really looked.
And that 5c crack is the highest line on the wall! I doubt I'll be going near it anytime soon. E grades territory. Have you noticed how a lot of the lines on the wall have one last tricky move to grab the top? Adds spice/colours the trousers.
Try old man Andy Kay for beta, he's always worth a shout, you'll probably remember him he gave you a load of help with the Brownstones Guide.
Yeah I've been meaning to ask him, just haven't got round to it yet as I got sidetracked by other problems. Plenty to do on that wall, plenty not in the lancs guide too. Every time I've been I've discovered something else. It's a fantastic piece of rock, really deserves more attention.
