how do you choose to call???

what i mean is...what makes you go from soft sporadic calling, just enough to let the bird know theres a hen in the area, to agressive, loud, excited yelps and cutting and that sort of calling??

my buddy was hunting the other day and said he had 2 birds 150yds away..he was calling soft and not real hard...they would answer but werent real fired up or anything serious...but then another hunter moved in...he could hear the other hunter going nuts cutting and yelping hard and loud and excited...those birds bee lined to the other hunter and he killed one...


thats one part of turkey hunting i really dont "get" yet....ive always went with "less is better" and clucks and soft yelps and leave scratching is really about all i do. i just have trouble figuring out when getting excited and agressive will pay off..

any thoughts? tips? anything...im sure theres a time and place for each type of calling...i just never figured it out....
