Although a few years ago I messed around with a lot of scopes at the range, I keep finding myself with 2.5-8s on my rifles when I actually shoot at game. (Which is far from often enough.)

So far, I've shot everything on either 4X or 6X. Everything I've shot on 4X I could have shot on 6X, and vice versa. I guess for me this means the 10X top end wouldn't add anything, and if someone made a fixed 5x36 with the same tube dimensions I could just buy two or three of those and call it the perfect compromise!
