A lot of you will disagree, some of you perhaps vehemently, but "instant choke selection" is the most overrated advantage of two-trigger guns. On the whole, hunters worry way too much about choke, and they tend to overestimate yardage in the heat of the moment anyway. I always remember my first pheasant hunt with a friend who is a classic side by side shooter and a very experienced uplander. I kicked a pheasant up over his pointer, and, as it was my turn, I waited to let it get out far enough to shoot with my Improved Cylinder 12-gauge. When I finally shot, so did he. Both patterns hit the bird at once and it poofed in a cloud of feathers. While it was still edible, I had to eat around a whole lot of pellets.
