It's about time someone pointed this out! I've read about so many people using Captains when for a few bucks more, they could have had Flagship. If UV is such a big deal, then why do so many of you use the "inferior" of the two products? What does Captains have over Flagship, apart from price? Unless someone gives me a really good reason, there's _no way_ that I'm going to use the slightly cheaper product. Talk of "tan lines" from minimal exposure to sunlight has me paranoid.
