Has anyone tried Spectra PhotoSync for tint? From reading, it sounds like the i3 is difficult not matter what material you use and I'm torn between the 3M Crystaline or the Spectra PhotoSync. From what I can tell, the 3M has great heat reduction but the PhotoSync is almost like transition sunglasses in that it darkens in the bright sun and is clear at night (which I really need since I have trouble seeing clearly at night).
