I've used expensive stff before, but unless you're life will depend on it not breaking, I'd stick with a burris (or equivalent) standard or dual dovetail base (1 or 2 piece). And I'm a huge fan of burris signature rings. Weaver style bases with burris signature zee's would suit me, too, but there are less parts to come loose on a dual dovetail set-up. I really, really like the signatures.
