I have found when hunting an area, where there are several toms, but only 1 or 2 may be dominate, that the jakes and subordanant toms are reluctant to come into a set up with a jake decoy in it. I'm not sure, but would guess they got a woppin from the big boys, and don't respond to the jake decoy, for fear of another woppin. I strictly use 1 or 2 hens, maybe 3 if it's early in the season, but no jake. I have never called in a big tom with a jake decoy setup with hens. However, I have called in several big daddy's with just 1 hen decoy, and twice with none at all. That said, every place is differant, and every hunt is differant, and what may not work for me here, maybe just the opposite there for you. If I were you, give a jake set up first thing on day one, use it till late morning, then, if nothing is happening, take the jake out, move a little, and reset up with just one hen, and call softly. Alot of times after the hen's get bred and go to the nest in late morning, you can find a lonely tom, and coax him in. good luck, I hope this helps.
