I can't agree more regarding giving the gobblers some distance and letting them get down off the roost. I gave up a long time ago trying to aggressively call a gob off the roost. I stay well back from the roost trees and just let them know I'm there. The vast majority of my successes are 1-2 hours after flydown when the flocks are moving to feed. By then, the gobblers are much more interested in coming to a hen they can't see.
Funny thing. Once I gave up aggressively calling to roosted gobs, I found my little tree calls and such were more seductive than I thought. As a result, I've taken more birds coming directly to me from the roost than when I was up close to the roost tree trying to out-do the hens.
Another thing I've seen is that if I start well back from the gobbler's roost and then get up and move closer (say from 300 yards to 200 yards) that gob may hop down and start running to me.
