i have the b-mobile and love it. it is very effective and they put on a great show. but to be honest i have had just as much if not more luck with 2 hens and a standard jake. with one of the hens in a breeding position.
One of the problems with a full strut deke is that most of the toms we call in are most likely not the dominant turkey. they are usually a submissive that is hoping to horn in on a piece of action. a full strut sometimes scares them away.
