Rattling along with some grunting is king of all calling in my book. As far as advice though i would just say go out there bang some horns together and you will figure out what works best for you. I have rattled up multiple bucks for myself and other people. I can tell you there is nothing better than a buck (any size) charging into your lap looking for a fight. The main thing is just make sure if you are on the ground you have your gun set up to shoot quick. Cheers
