You learn quickly that you need both. I try calling them in, but if it doesnt work i ditch the decs, and just grab a call and my gun and go. Couple seasons ago i got my bird by racing it around a mountain. It went over the top and i took the path, got to where i was hoping to be able to ambush it and it was standing right in the middle of a clearing, it turned to run, so i took it. Ive also spent hours working a weary bird in using a call.
