I have a Brown MS and went with 3M Crystalline installed by Cactus Tint in Scottsdale, the same place that had previously done araxara's Brown MS with Photosync. I am very happy with it and their professionalism, service and quality. I was going to go with Photosync because of everything I read here, but Cactus Tint and my husband talked me out it - mostly on the basis that it hasn't been around as long as 3M, coupled with the fact that I have Crystalline on my BMW 6 series, so I knew what I was getting. Cactus was happy to do Photosync for me, and was pleased with araxara's - so it wasn't really anything 'against' the photosync per se.
Anyway, I went with 35 on the sides and rear window (the darkest they offered, the legal limit in AZ, and also what I have on my BMW), and 70 (or was it 75?) on the windshield. Similar to other statements here, Cactus Tint said you really couldn't totally avoid the purple-ish tint on the rear window because of the existing coating and the slant of the window, but his opinion was that the purple would be less pronounced with the Crystalline - I don't notice it at all, personnally. They also had something even lighter for the windshield that I was considering, as i didn't really want 'tint' on the windshield, just the heat rejection. But he encouraged the 70/75, and I went with his expertise. No regrets at all.
I did not get the pano roof done - for all the reasons mentioned here. Tesla rep at the Scottsdale gallery told me it has Crystalline on it already - I don't know if that's true, but it definitely has something that blocks the heat very well already.
I don't have any pictures to share....but I really should make a point of getting some.
