In reply to Sam Marks:
I found it pretty tough, having done quite a few E3s before (but, in fairness, probably none that required steep jamming). It's well-protected, so if you fancy a go then you have only the onsight to lose
I found the jams surprisingly good, but I had to make a very awkward and long reach to get to the good ones. I know some people have laybacked the lower part of the main straight crack; I didn't try but it felt improbable when there. I then just got really pumped trying to get gear in on the steep jams.
I haven't been back to get it clean yet, but it's an awesome wee climb, no doubt about it.
Good luck!
Pete.
