Probably all out deep water base jumping in wacky hats
I dunno any beta but perhaps it's just very hard for the grade. I've belayed someone on it who failed and the other weekend, a couple of mates both didn't do it and they're not shy of on-sighting E6. One of them had on-sighted From a Distance the previous day.
The answer is to layback the opposite way round to what seems natural. I can't remember which way that is.
I spoke to Nic Sellers last night (who also failed on it recently). He said he thought you had to head rightwards and get you left foot very high to get into the layback. He thought it felt totally desperate too, which doesn't bode well for the likes of me...
