Won't lay claim that I'm a "more seasoned" guy.....though my whiskers are comeing in more gray lately
As far as you're strategy goes,, sounds like you're on the X and those geese will likely want to be there again until you shoot 'em.
Concealment is always most important, if a hedgerow offers that, AND taking into consideration the wind direction for the kill hole, I'll take that anytime over a "bump in the field" laydown that those geese didn't see there the last time they visited.
As for the dekes, I always feel that "someone has to start the X feeding party",, meaning you having a half dozen full bodies is like a small family group that gets there earlier than the big group, that's what I would use.
Don't do a lot of calling either, especially if you're in a hedgerow any distance away,,, a few clucks when the first birds are spotted in the distance and then clam up as to not give away your hide.
You'll likely get more opinions on this from more seasoned that I......Good Luck, kill a limit...could be your only chance for that field.
