Let me throw one more wrinkle into the thread. I prefer a 24" tube, but have nothing against a 26" barrel. I realize the 28" gives the maximum sight plane, but is there any appreciable difference between a 24" barrel and 28"?
There is, but it is primarily balance and the extra weight out front to "help" you with swing/follow through. As for sighting plane, you already have an extra 3 plus inches for the receiver, so a 24" Benelli is roughly the same "sight plane" as a 28" o/u or SxS. For strictly waterfowl I prefer the 28" on a Benelli, but if it were mostly going to be for turkey and upland, I would go 24" or 26"; the shorter if mostly turkey, the longer if mostly upland.
