Not the best pictures to show tint, but I already had these uploaded on my Flickr account. This is 30% Llumar Stratos.
Keep in mind, depending on the lighting condition, interior color, overcast/sunny day, tint % is very subjective. As you can see in the first photo, the tint looks quite dark (in parking garage at work) and then the second photo appears to be lighter (sun is shining in through the windshield).
EDIT: Edited my post to show the pictures. For some reason the link was only showing up.
