I think you have a fine set up from what you mentioned you already have.
Let me add this and you can make your own choice. I have the whole line up of DSDs, hens, jake and strutter. Depending the phase of the season and how far I have to carry stuff depends a lot on what set up I use. It has been my experience that when I have 2 or 3 hen decoys out that almost every time real hens come to the upright hen to sort of "challenge" that decoy. Sometimes they may drag a gobbler along with them, other times if it is a lone hen the ruckus she makes and the excitement in her calling has fired up a gobbler and brings him in as well. Would I have gotten any of those gobblers without the live hen reaction to that decoy, I have no idea what may have happened if it were not set out. Another thing I have only witnessed one time is a hen strutting, and that response was from aggressive behavior to the DSD upright hen.
In saying all of that, you have a fine set up with the ones you mentioned. However I can think of several responses that I got to watch unfold before my eyes that may have never happened without that upright hen being in play.
