Window tinting, how dark is too dark?

[Jet-Star]

I'm getting my windows tinted as soon as I can make a decision on this and i'd like a bit of input & advice on what to get.

I called up the local tinting bloke and got a quote for my EF, $440 for all of the windows including the front in the "Privacy tint" which he said was 17% darker than legal.. But im a bit worried i'm going to go and spend all this money on getting dark dark windows then getting pulled up for it and getting a canary.

Should I just stick with whats legal? Or have people found the cops to be pretty good with window tints? My car is clean and I never get harrassed by the local police so I don't want this to be the one thing they don't like and start picking on me for... How ever I've never heard of anyone being picked up on their windows being too dark so i'm thinking I should be right as long as I don't draw attention needlessly.

What are peoples thoughts on the subject?
