Truth is, it's a love affair. I've owned and shot, in the field o/u guns but just cold not fall in love with them. And, I don't have to. Further, in rough shooting, I am not convinced of the superiority of an o/u, but if I could bag 20% more birds with one, it wouldn't matter. The whole sport is a love affair.
To many of my hunting buds the sport is a game where one keeps track of scores; not me. I am there for far more personal reasons than keeping score. Shooting a sxs is a connection to my father and grandfather. So is the entire sport. ;-{>8
