Well a Strutting TOM can be real good or real bad so be aware of that. By that I mean I have had Toms shy away from my strutter.
Then at other times they have come right on in!
I like groups of 3. A Strutter, a laying hen and a feeding hen. Recently I have added a 4th feeding hen.
If I think the Strutter is causing me harm or making birds shy I take him out of the picture and use the 2 or 3 hens.
I have witnessed terrible luck with a Jake decoy and have since got rid of mine.

Above picture was taken from the back of my strutter looking back at my blind. The strutter is 12 steps away - the full bodied laying hen is 11 and the 2 feeders are 6 steps away. I like my decoys close for several reasons. Main one safety!
You can see I do not brush my blind in at all.
This is a early morning setting and the blind is facing west because the sun will warm this edge of the field up first and is a strut zone!

Above is looking from the blind.
Decoys are on my right.
Now this has worked for me many times - and in later seasons I do remove the Tom
I always have the Tom facing me - hens facing away or off to one side. I like the bobble hens as they have nice movement.
The full body old carrylite hen is placed right onthe ground and I have a 4 inch stake in her belly.
Hope this gives you some ideas to try - but what ever you do - make it look real -
SAFETY
Never place decoys directly in front of you. There are some who don't know the difference.
