When I'm working high pressuerd birds I've found that the less you call the better. When a gobbler sounds off on the roost I'll answer him with just a couple very raspy yelps and some soft clucks, then go quiet, just let him know your there. After he's on the ground, I'll give him some excited cutts and clucks and a few kee kees, then go silent for a bit, sometimes I won't touch a call for an hour. Patience is a must on high pressuerd birds, if that gobbler knows your there he'll be checking you out, it becomes a stand off and if you move he'll stay put and wait for you to come to him. If your working a close bird you may have to stay put for 3-4 hours sometimes. Patience, patience, patience.
