BTW...if you want to go real light, and only want to use one decoy(especially early in the season)....I'd go with only a jake.
Back when I still gun hunted I had very little decoy reaction to my lone hen. One year, before the season started I converted my hen to a jake with the help of a little cat whiskers beard, and some red and blue magic markers.
The reaction to the "jake" was amazing!!
Even now no matter how many hens I have out, a tom will 100% of the time walk right past hen decoys to get to the Tom/Jake decoy...100%!(my experience)
