When I use them, I use a jake and a hen. I've had mixed reactions to them over the years, some good, some bad. Last year they worked to perfection on opening day. I almost always use them on the first setup of the day, when I can get out in the open and set them up under the cover of darkness. Then there are times when you just don't have time to set them up or the cover won't allow it. But they are worth the effort most times if you don't mind packing them along with you.
