After much research and posting here on the forum I went with the Warne Maxima series of bases. They are made of solid steel and are blued. No whimpy aluminum bases here. I purchased a base for each of my barrels and a set of regular rings and QD rings. You will probably want to go with medium rings regardless of the size of you objective - unless its a larger one. I'm not sure if the low rings will allow you enough thumb room to cock the hammer. Mediums are just about right.
They're not cheap, and they're not light either. But, I feel that it was money well spent - they're solid as a rock. My 2 cents worht.
