IMO, the easiest snows to decoy will be the last ones through in mid november, right before freezeup. These flocks will be nearly all juvies, and you can cut their ****s with a spread like you've got if you find them. You'll know you're in the right birds when you won't kill a white snow or whiteheaded blue out of and 80 bird limit. If you find birds like this, leave the robo, flags and other b.s. home. If you set up and the birds dont respond, you're a week to early and you're still hunting adults. I had a 6 bird day over thanksgiving acouople years ago, called my buddies cause I couldnt believe there were still adults around, and they shot 120 the same bluebird morning 60 miles north of me. Just goes to show that having the right birds is FAR more important than the right spread. Save your money for vacation time and gas.
