Free: Contests & Raffles.
For puddlers I like 12 - 24 mallards (closer to 12 if I can manage) with a handful of GWT and wigeon mixed in.. If I owned a 6-12 pintail I would throw them out too, depending on which spot I'm hunting. Just my I'm clueless when it comes to diver hunting spreads.
I think that you should have a setup unlike anyone else. As you noticed everyone said 1-2 doz mallards, usually hotbuys, a couple widgeon, pintail and gwt. So what if you showed up with 1-2 doz Pintails, 1 doz widgeon and 4 drake mallards, 1 wind decoy, 1 jerk string with 4 decoys attached, and tie your rigging onto different spots on your deeks. As the ducks fly over your spread will not look like every other plastic flock they see and will come in for a closer look.
