Was trying this today like this - rh above lh on arete, rf outside edge on gash smear near arete, then quickly lf toe end on tiny nubbin above rf. you then start to barn door immediately so i was jumping for the top which i was hitting but not holding as i had no skin since i spent two hours trying a sequence using a monumentally gash sidepull to the right before i was using the said sequence.
Not sure how many have done this, but i would be glad of some beta just to make sure im doing it right. BTW the guidebooks are spot on with this one - Loads harder than it looks!
cheers,
Tom
