We actually tried that this year, putting out more pintails for visual purposes.
If someone didn't know, they would've sworn we put out acid in the water. I've never understood that, and it happened every time we tried it. we retired our pintails from that hole for the year. (been like that for 10 years). Who knows what/why/or anything else for that matter but the ducks will literally not use it (and pintails are killed there every year) when we add off colored dekes. It's weird I guess, just something I've noticed over the years. you can use the same spread (w/ pintails) in the field adjacent to it, and they will flock in.
As far as the largest spreads, we put out 16 dozen one morning this past year. 8 limits came of our efforts. 10% of the shots where feet down. The other 90% were hail marry shots. We KILLED but I like the moment when the wings rotate in a backward fashion while their eyes strain for a landing area feet away.
To each their own I guess. it is effective, and for those that like shooting, it works.
