If he was traveling with a jake, then most likely he doesnt mind them, so i'd just use a hen, but you might want to have 2 hens in one area, and then have a jake off to one side and that way you can gobble to him after playing with some hen calls, to get him fired up...like for example:


..................................... you setup here
.............................../\................................../\
................................|................. ..................|
............................15yds................. ............15yds
................................|................. ..................|
...............................\/..................................\/
........Hen Decoys here <-----20 yards +/-----> Jake Decoy here

This way he has a choice and so do you.
