I have always used a 28” barrel for waterfowl. The last 15 years or so has been with a SBE2. I like to use extended chokes now as well. With That platform and my LOP; it was a long shotgun...
When I decided I no longer shoot wanted to shoot 3.5” shells, I opted for a 26” M2 with the extended Carlson chokes. I find it to be the better combination as I still have a good balance of speed and follow thru.
I am also hunting in tighter cover for ducks and less field hunting for geese FWIW.
