In reply to JH74:
Both Off the Mark and International Kidney Dealer are probably around 7c. Maybe. Maybe easier. Hard to grade these things. I graded IKD to be consistent with OTM. OTM isn't so bad once you know where the holds are but, as I perceive it, it's a hard onsight as most holds on that wall slope outwards, and finding the ones that don't is a tiring business. Same goes for IKD. If they're chalked, then it's going to really reduce the difficulty. Both routes are quite runout (esp. IKD), but then again, if you fall 10 metres into free space, is that a whole lot worse than falling 1 metre? And does a longer but safe fall warrant a higher grade? It's so much more cut and dried when you either hit the ground or you don't!
It might be that both routes get onsighted (they do have sufficient gear to encourage an onsight) and settle in at E6. Maybe they won't. In some sense it doesn't matter too much, they're both great and it's an absolute privilege to put up quality new routes in such a sublime setting.
