I will also add after fifty years of wing shooting the so-called "longer sight plane" of longer barrels makes some sense while in the easy chair at the typewriter (this was espoused in the sixties already), I have found longer barrels slower, heavier, and not one feather more effective than, say, a 24" tube.
At least for me. Upland shooting usually requires quickness but then I'm a "snap-shooter" not a point-and-swing guy.
