It's completely situational with me. I shoot TSS in those states and areas that have no small shot size restrictions. I revert to lead, hevi-shot, or heavyweights in those that prohibit smaller shot. Where 6's or larger are required, I shoot Win LBs. Where anything larger than 8's must be used I shoot Hevi-Shot 7's or dip into my stash of Fed HW 7's.
For the record, I've shot turkeys this spring with everything from #5's to #9.5's. None of them cared...
