My only complaint on weaver is the high gloss finish. never had one fail. Twist ins look good, but repeated R&R will wear them. Leupold QR can also suffer wear from frequent R&R. The long savage spacing can be an exercise in patience to find a combination that will take a short scope tube. For this reason one piece twist ins or multi slot weaver / picitiney are common. I like to hit something that looks good but I see no advantage to spending lots of money. Even on a 7mm Rem Mat striker that jumps through the air I have had no recoil problems in any base. I like and use a lot of Burris Sig Zs but I do dislike the small cross screw. no fails, just looks to small. EGW and Zs are on the majority of mine.
