Really your choice. I happen to like the smaller Mini on my camera, but many others like to put a Flex on the camera, and get the benifits of the same hardware at every location. Many also prefer the standard AA batteries in the Flex over the coin cell in the Mini, but I get fantastic battery life in my Mini, as long as I remember to turn it off at the end of the day. If you leave the antenna folded down on a Flex, it is really not much bigger than a Mini, and you can always fold it up if you need the better range.
