More than half of the crimp under the roof broke off this afternoon. Shame as I had just failed on the very last move the go before. Post breakage I had a play (just to check if it was still climbable) in its new state and managed to climb past the crimp. The crimp which was always pretty vital is now rather less friendly and the problem is now an even tougher 7b+.
If anyone feels it is worth sticking it back on, I have the piece that broke off. Personally I don`t think there is much point. I don`t think it would stay on long due to its shape, it is still climbable, the rest of the hold looks solid and it may even have become the 7c is was always meant to be!
