I bought a Super X2 a few years back in 3 1/2" to use for turkey and waterfowl. I debated between the turkey gun and the duck gun. I got the 28" waterfowl edition because I figured the longer barrel would be better for wingshooting geese and ducks. It was a great wingshooting gun, and it patterned turkey loads awesome. But when I got it into the woods in the spring, I was really wishing that I'd gone with the shorter barrel. That long gun snagged every branch I walked under. I killed birds with it, but it was not what I would have called a perfect gobbler gun.
My new gun is a 535 Mossberg with a 22" barrel. Much nicer in the woods, short enough for the blind, and it patterns awesome with the Indian Creek/Hevi-13 combo.
