S&R,in my mind the two go hand in hand(hunter,caller)I've known and still know quite a few fellas that have actually won a callin contest or two and then get to the turkey woods an have no idea how to read a bird or dont really understand turkey talk to be an effective caller!Its great to be able to produce all kinds of turkey talk,but knowin when to use it is what makes it effective,and in my mind thats part of being an effective turkey caller.Obviously gettin aggressive with late season birds works effectively for you,but for myself I've found most of these late season birds have been yacked to death by pressure,and if you get aggresive with them they have a tendency to develope a case of dreaded lock-jaw! Pressure,hens,terrain,private property,# of active birds,etc in my mind all play into how we approach a bird in calling to him,and I do agree with all here that experience is the key to becoming a good turkey caller not just how sweet a music we can make on our turkey call.Simply because experience tells us how to communicate with him.
