everytime I have done the snort wheeze the deer has split like thier tail was on fire. I like the buck roar call but I use it like you would any grunt call. I like the deep tone . The deer seem to respond to it. I also use a grunt call when I am rattleing. I like to start out softly and then get louder If I get not action. same thing with the antlers. I think you can call to much but many feel you can't. I like to hit the call about every 30 min. or so. If I have deer movent or I see the deer I usually don't call at all unless I am sure he is leaving my area and then it is "what have you got to loose".
