With my voice, I can do barred owl hoots, crow calls, hen sounds, and gobbles (I'm not joking). My weakness though is that I go hoarse from the hen sounds. So my overall plan is to get him gobbling with crow sounds and then get in as CLOSE as I can before I begin making the hen sounds, because once I start with the hen sounds I'm only good for about 35 minutes before I'm done.
I also just went out and bought a hen and jake decoy. My hope is he'll kick that jake around in the dirt long enough to give me the oppurtunity to move and draw my bow.
