I like the extra wide "tactical" rings and even run quad tacticals on one rifle, generally speaking I like anything without "inserts. In case you had not figured it out: I had a ghost plaguing one of my systems for awhile and I waisted allot of ammo trying to find it, It turned out to be the signature rings and they just would not lock it down, it kept sliding and sliding back to it's original location so identifying the problem was a bear. In defense of the signature rings: they were not the only ones to fail on that rifle and that rifle is the one that needed the four tac ring set up. For some of the stuff I do and the significant priority I have to place on a reliable and uncorrected first round hit, the signature rings are just not a chance I will take again. I have come to the place were I think scope rings are an area to invest, they are a great spot to go into "overkill". I have to be ultra confident in my gear in order to take the shot at all.
