It's very American to go with the more is better approach. tractorlegs, you're right on with your theory of relativity.

fizbiz, kudos to you for reminding us that more may be better but enough can be enough and a little modest luminosity can go a long way in some situations. I attempted to elaborate on those situations, which I don't think bjorke even read because he disputed us by basically repeating things I had already said. Neither of us pretended to present the grand unified solution to all luminosity needs.

Anybody want to go halves on a Bentley?
