I hate 7's with a passion. I would do some terrible things to sport a 14 over the 7's. Im kind of lying, if the price was right I'd get a set, but I'm around three little girls and a wife all day, so the whole concept of being dramatic to make a point is wearing off on me.
I do not like 7's for driving, fighting, wearing for extended periods of time with a poor helmet (ach...a nice helmet makes 7's a much nicer piece of gear IMO), walking, or transitioning between light and dark areas such as in a city or in and out of buildings on short notice.
Things that 7's are good at is sitting in a lawn chair that has a high enough back so that your head can rest on it while you stargaze, prolonged observation from a fixed position, using handheld with a magnifier, and getting in to Gen3 at a more affordable price than 14's.
