I doubt they'll pull if you aid off them. I was mostly concerned about the rock for this reason:
"seem to remember a crack through the rock that passed through the bolt hole."
I thought that bit would be dodgy in a fall. I reckon, in general, if the wall is vertical (ie, not carrots in a horizontal roof) and you're aiding, it would have to be very, very soft rock for problems. |
