O.K., so I just got a drill. I have read many online battles about the great bolt wars, and although I have a few local spots that I would love to put some bolts at (even if they are just for T.R. set ups) I certainly don't want to be "that guy." After a friend told me about these removable bolts, I thought that would be a great "lower" impact solution. I'm just curious if anyone has used them or knows anything about them. I know the 1/2 inch and 3/8 inch are the only ones rated for actual climbing (1/4" + 5/8" are only for aid), but that's about all I could muster up on them. I guess I'm just looking for as much input on this subject as possible. Thanx.
