sillies work wonders in the feild hunts just keep an eye on them. i get them to glare alot, even on days were we have solid overcast but the sun is still trying. that small galre kicks them birds up faster than i can pull the trigger. now when everything comes together and i dont have a glare on the sillies. man what a hunt i get out of em. just pay attention. just like goose hunting in general, you have to pay attention to all details of the hunt. good luck though hope they wprk kell for you.
