FWIW & IMHO,
Dual Dovetails are a very hard system to fault. I prefer unitized one piece mounts similar to the ones made for Chandler, however, they have gone out of business and I dunno if anyone is stepping up to the plate to carry the mount. I'm fairly certain they are made by Badger Ordnance. Richard Near, who can be a mental furball, also makes a very nice version of this mount called the Alphamount. Here are a few photos from a forum member some four years ago...
This is a DD Ross Unitized Mount that is no longer available. The benefit is using all four screws, versus three on factory one piece dual dovetail mounts. Granted I don't know what it really offers over Dual Dovetails on two piece bases.

I greatly prefer Talley TNT rings and bases over Warnes. That is if you want to go with a vertical split ring. I started with them when they were Kimber Rings & Bases and went on to use them on my 82C after they formed the second company on Kimber of America, Made in Oregon. If I had a reason to dislikes Warnes it stems from their powdered metal construction and tendency to attract rust. Especially in the matte finish which is overly rough and gives moisture a place to hold. Talleys are made of bar-stock and I think they are the better-looking ring without question. If you can stay with a 1" or 30mm tube you can get both in Stainless. Not plated chrome moly. 34mm TNTs are only available in Chrome Moly/Blue. That being said the metal grain pattern is tight and the finish can be somewhat muted though they are smooth and are not as rust prone the Warne Product. IME.. That said vertical split rings can be difficult to get the reticle level due to their tendency to turn the tube on tightening. Not to mention turning the scope in the rings is an almost guaranteed practice for ring marks...
If going to a Picatinny rail and rings Badger Ordnance has yet to be excelled(IMHO). I've installed a couple hundred sets as a Schmidt & Bender dealer. The finish is not up to NEAR, however, the tolerances are superb and I have never had to lap the first set. Nor have I left a ring mark on a tube to my knowledge.
I've had pretty miserable luck with Nightforce Alloy Rings and worst of all their unimounts. Not bad once installed and heavily lapped, however, they are a nightmare on being off spec for the scope tube and unimounts are often bent and bowed heavily. Installation on a rail and proper lapping is about the only say to keep that product from pinching the tube and imparted a great deal of unnecessary stress to the scope. Their steel rings are good quality, however, I would take Badger every time...
All in all Dual Dovetails properly mounted(lapped in place) are hard to beat. They were my first centerfire ring & base configuration and I still thing they are superb. Be sure NOT to wipe off the copper anti-seize from the tenon. Doing so will lead to galling.
The ultimate ring and base system, again IMHO, is D'arcy Echols custom mounts he installs on this Legend AND some Classics. They add a third screw to each one piece lower ring & base and are quite attractive to the eye. Not to mention as stout as anything ever made...
Best of luck...
