I've mostly only used leupolds, single dovetail, but I kinda like the dual dovetail, I rarely see them though.
My last 2 sets I've bought have been Talley's, 1 screw lok, 1 lightweight 1 pieces, they're very nice.
Use lock tite, and do you lapp the rings? something to consider doing....did it for the first time on my last set of talley's pretty easy to do well.
I use Leupold and some have been on centerfire rifles for 40 years with no problems.
Be careful with loctite - use the blue, which is removeable.
