I had pretty good luck with the B mobile. I used a real feather tail set up like a jake. I used this in a bredding look and the gobbler just couldn't take it. I think it is like any thing else you have to get a feel for the temp of the birds in your area. My best luck came late in the season. Early it was tough just hearing a gobble, then bang.
Can't wait to hear the first one here, but we still have 2 feet of snow on the ground.
