Correction, the Roadmaster does not get darker than the Superfly or the Fatboy, but starts out darker and gets as dark as those two. That is a result of my scientifically conducted FeS testing facilities arduous side by side test. (I took them out in the sun and watched them turn and decided it gets just as dark and not darker)
End result, three nice sets of glasses (Roadmaster converts to goggles) Two go clear for night driving, the Roadmaster stays a bit darker but still suitable for night driving. One set of glasses that covers you both night and day with out having to changes lens or dig for another set of glasses when you get caught at night.
More tests to come!
