Me, too. The only exception I might would make in favor of a 16 or 20 is the early teal season, in which you can shoot nothing else except maybe a woodie in states where an early woodie season overlaps the teal season in September. I was shooting beside a gentleman, and I mean gentleman in every sense of the word, in a duck blind on Reelfoot Lake last September. We were gunning teal ..... blue wings. He was using a 20 and he did just as good a job, if not better, on them than any man there using a 12. No crippling problems, and the 20 was very quick for those little darting, jiving blues.
