Correct - getting back to the original question - how would I rate these bolts? I would agree with your 3/5 assessment and everyone's comments (0=unsafe, replace immediately, 5 = the latest hardware installed by Greg Barnes himself). So - nice to replace, but not a safety issue, and probably not a top replacement priority. I see bolts like those all over Tahoe, Yosemite, and local crags. As Sam points out, you really don't know the true condition until you start the replacement process and examine the bolt inside the hole. Thanks for starting the thread!
