I sometimes make a foray onto public hunting areas during the duck season. You can pick out the guy who cares about his choke from across the lake. He'll be in the wrong spot, wailing away (blowing) on a double-reeded Wal-Mart special with no scratch, terrible cadence, and no idea how to respond to ducks. Then he'll stand up and unload his 3 1/2" mossberg (or maybe a 3 1/2" 1200) at 60 yards, probably at bluebills, and when nothing falls he'll blame it on a)shot size or b)choke.
I've guided waterfowl and turkey hunters for years. I've hunted with state and National Calling champions. I've hunted with competetive shooters. Most of those guys are real killers. I have never heard a single one of them talk about their choke. For waterfowl I put a modified in and forget about it. For turkeys I put a super full in and forget about it. So many other things have more impact on your hunt. Hell my favorite duck/pheasant/quail/dove gun has (*gasp*) a fixed modified choke.
I've got 2 turkey guns I use regularly, an 870 and Super Black Eagle 2. The SBE is for people who fly in and can't bring a gun, or family and friends to use. It has a ported super full choke in it. The 870 is my turkey gun, and it has a non-ported super full in it. Patterns? Couldn't tell the difference. Recoil? Couldn't tell the difference.
