RE: gobbler off the roost
That particular day, I may go to a different bird or (depending on property lines and how hot he is) I'd try and figure out where he's going to and make a big (250+yds) circle and try to get in front of him. If you can set up where they're going, calling is much easier and you'll be more successful. Pre season and during season scouting helps in this type scenerio and will help you to be a lot more successful.
