just my 2 cents on the re-bolts, a damn good idea but like offwhite says it can be hard as hell to find the next hole, same crap as bat hooking. also the worst thing about em, ever tryed removing a re-bolt that was hung on or fallen on? its damn near impossible, no wonder ive seen more fixed re-bolts than ones hanging on peoples racks. but im going to stay with porter here, if your drillen your still harming the rock so might as well fill the hole with something that will serve its purpose.
