On the these calling contests, can you use more than one call? I know there are categories for mouth and friction, but like, could I yelp and cutt on a call, then change mouth calls and do a kee kee?? And another question, how do all these hand gestures come into play?? I"ve seen some snipits of contests on the TV and have never really understood what purpose all these hand motions play....I know when I call, I place a hand beside my mouth, but I do that more outta habit 1. to reflect some sound toward my ear so I can hear it better and 2. to pitch the sound out towards the gobbler...
