And these quarries were abandoned at 10 years ago and all are granite rock. I try to making two new routes at last two week. Here is some photos. The difficult are marked at 5.12a and 5.10c. Should i make new routes or stop it and closed the route? Help me plz. Thanks all What type of rock are you bolting and how hard is it? Once again I would like to reinitiate that the bolts you are using are ONLY for hard rock and they can fail under bodyweight alone in soft rock. And why do you think shear strength would fluctuate between soft or hard rock?
As far as the bolt pulling on body weight in soft rock:

The bolts in those videos are very similar to what the OP is using.
