In reply to sjc:
It's true, it's very hard to read the moves out of the top of the crack and they are the sort of sidepully moves that are totally committing and would be desperate to reverse. It's 'only' F7c+ climbing if you have it wired, but it remains a really hard route to on-sight. It's not like it's completely 'safe' either, as it's desperate to get the gear in through the crux section, so actually there's a massive runout - hence the iconic photo of Glowacz 15 feet above his last piece! I don't know why it's given the split grade... I can only think the dark forces of Wesh guidebook writing are at work. It's solid E7!
