When I had mine done in MD, I went with the darkest possible which was I believe 35% on the sides and 5% the rest of the way back. The back is very dark at night, but I can still see enough using my side mirrors that I don't really worry when backing up. During the day I can see through the rear just fine (I gotten used to it). On an Ebony, the dark black looks great, in my opinion. The mirrored tint might look OK on a Silver VX, but I'm not sure if I've ever seen one to know for sure.
