SHOJLUS: I had 35% on my Deep Impact Blue SEL and although sold as 35% it tint metered at local P.D of 45% I could have gone a little lower. I am holding my tint on the new 14 SHO until I get to Texas and looking at 25% I would go with what's Legal avoid attention. That being said I wouldn't recommend darker than about 25-30% just to still keep some outward vision especially at night.
FYI Magnetic is my second choice of color, the 14 SHO I got was a leftover Ingot Silver and will look good with 25 or 30%
FYI#2: If you are looking for eyebrow tint remember the AS-1 Line in the upper corner. That is a reference line for tint, although mine was legal in Maryland down to the AS-1 Line I had to have them trim back. After installation even though legal it felt like it was obstructing my Periphal vision so they trimmed it back to 4" which kept it dark above to keep out sun/glare but still able to see out and not get distracted with the line below. If legal I recommend 5 or 0 if available for the eye brow tint.
