Let's see if this helps you for a set up.

What I find is the Tom and hens like the East side of a field as that is where the sun will warm it up first. So I look for a hiding place there. No place to hide a blind is in order (if one so chooses).
I also take specail note of where I consistently see hens. Tom will surely be there.

On some extreme set-ups and not to be busted or bust birds - I have gone in at 230AM without a light to set up my blind and wait for daylight. I only call softly IF I hear the Tom. I use 2 to 3 hen decoys in late season and at times a strutting Tom. The tom may or may not scare the bird. He may just come charging in. If sub dominant he will not.
Decoys are set close less than 10 yards from me. They are set off to one side opposite to which I beleive the Tom will come in so he will have to travel past me.

But the East side is key.
