I just got my light tint DB a couple days ago. Absolutely love it. Wouldn't have gotten the darksmoke, cuz the light smoke is actually quite dark.
Makes a noticeable difference at highspeeds, and I think it actually looks alot better. If there is any nitpicking to be done, it's that it vibrates a little from the wind. But then again, I think stock windscreens vibrate too.
