Sean: Dont' do your science homework on cable purveyors' Web sites. Karls is dead right about skin effect--it's inconsequential at audio frequencies. If you like solid wire, use solid wire. Just spare us the "scientific" justifications.
As for corrosion, I have my doubts about how important corrosion is on exposed surfaces, which are, by definition, not points of contact. But I agree with other posters who state that a good crimp is critical (and undoubtedly better than a so-so solder job).
