So something I have seen and read with the "Pretty Boy" and have heard it said that as soon as they see him birds head away. My first White Headed Strutter "BIG PUFFY" I made was in 1999 and from a Feather Flex Tommy Decoy and is small in stature, I have taken notice that Pretty Boy is a large decoy, I have never hunted over one but wonder if there is something to that... I did change to "King Strut" when he came out and doctored up his head and now added wings to the decoy by their design, I liked the detailed head they were putting on this decoy and that he was flocked, hunted him for a long time and in 2011 DSD released their Strutter, I picked one up at the end of the season and made several changes to the decoy including my White Head design. Just a note to this DSD did just release a Jake Strutter, already have mine and I am fixing him up! Wanted the smaller sized decoy for mobility.
I have killed a number of "late season" birds with my White Head and a single hen decoy, either my Feeding Hen or Upright Hen. This is one of my seasonal sets. My picture of my bird "Hook" is of just that type of set, a late season longbeard that was the dominant tom in the area. I'll ad the link to that story, it's a good read
If I knew more of your set and situation I could offer some advise from my expierences. "Nothing is ever 100% but I do run over 90."
Here's Hook
