V1 vs. Window Tinting.

Does anyone have any advice on window tint brands and how different tints effect radar reception by the V1. I have just moved to Florida and have decided that it is time to get the windows tinted. I am concerned however about the tint effecting the performance of my V1. I have talked to a few people that have their windows tinted and they don't have a problem but when I asked them what brand they had they were not sure. The local shops in my area seem to carry Llumar, Vista, Madico, and Solar Gard films. Does anyone have any experience (Good or Bad) with these brands or others. Are there any brands to stay away from because of scratching and bubbling problems.
