Hey Jon
If you are seeing several longbeards still together...i would....they love to pick on a unknown intruder
If you are seeing just a lone longbeard here and there...i would Not ...chances are he has been whipped and will avoid you.
If your seeing groups of Jakes....I would....they love coming in to investitgate a strutter.. i shoot more Jakes off a late season strutter than any
Let me say this about strutters....if your strutter looks real?? i would use it all season.. Gobblers keep strutting no matter what when a hot or potential breeding mate is near. Using a strutter only advertizes that "fake" situation...I use a DSD with real fan and butt feathers...it looks like a real turkey
i also use a Jake fan....Big Point here Jon if you digest anything i have sttaed so far.. Mount your Strutter LOW on the ground!!! do not have it High in the air TALLER than a real gobbler... push the stake in ground so Jake will appear smaller than real bird... this is huge and good luck
