In reply to harold walmsley:
I also did it in the late 80s and thought it was excellent. I was up there this summer and did some nearby routes. The bolts on Men At Work certainly seem well past their best and I remember thinking I wouldn't want to climb it with those bolts. I can't see anyone complaining if you rebolt it bolt for bolt, but please don't add any more. Regardless of the ethics, it's really not that scary (with trustworthy bolts!), otherwise it would be E4 or E5, and there are plenty of "proper" clip-ups on this level.
