Hi all, I'm going to be doing 50/50 mountain biking/road biking and would like to get a good set of sunglasses. Could some of you please give me your opinions on exactly what specific model Jawbreaker to get including lens tint? Also does anyone think the Radarlock XL's are better? If so, could you please recommend a specific model including lens tint? Also, Oakley's site doesn't say but does anyone know if either of these models are coated with hydrophobic or something similar (front/back) to deal with sweat./water? Thanks!
