I did Sardine yesterday for the first time in a few years, but I’ve probably done it 100+ times so am very familiar with it. That whole section of large block which you layback off just before stretching to the break below the belay feels loose. A loose hold at Raven Tor you say, so what? Well, if the whole thing came off a la the starting block of Mecca it could easily kill someone given the size of it and line of trajectory to earth. Maybe I’m being overly paranoid but I don’t see a downside to voicing my concern. Maybe it’s too big to glue/reinforce? Dunno. Would a crowbar behind it confirm or otherwise my suspicion? Anyway feel free to have a tap of it next time you’re up there but I’m bloody sure it didn’t use to feel that fragile.
