I usally throw at mixed percentage of all different head styles into the picture. Flocking your on the right days make a HUGE difference. When it is a foggy moring flocked heads make sure even with moisture on the heads there is no SHINE! also on the sunny days works awesome. I would Have all FFD's if i had the $. Early season around manitoba, they are pretty stupid and would come in to me if i was wearing a goose costume!
but when it comes to late season I found my flocked heads to have a huge advantage in the hunting compitions up here. The Horseshoe pattern decoy spreads is sometimes an OK move to make but i usally use family groups works good for me up here. I good way to conceal yourselves in cultivates fields is digging pitts(with permission ny farmer) And throwing a super magnums over your body, which works . Hope this helps and hope you guys shoot your limits next season!!!
