I'm currently using 3 EGW, one Weaver and one Ironsighter bases on my various Savages. One of the EGWs is the HD version made of 7075 Al, the other two are the basic rail. No difference in performance from any of them.

The Weaver base has a recoil lug machined into it and I like that, since Savage in general uses #6 screws for base mounting. It's also about the same price as the EGW, possibly less. The Blackhawk brand base is exactly the same base.

As far as the rings go I've got a set of the Weaver tactical rings on one of my rifles (not a Savage) and they work fine. Well machined, lightweight, hold the scope securely without the need to overtighten and inexpensive. Again, the Blackhawk rings are exactly the same thing.
