For me it's a timing thing. First thing in morning for the first hour and a half I'm usually silent. I will use doe bleat calls during early season to turn does toward me when bucks could be trailing. I use light rattling late October prior to primary rut. During the rut, I use wheeze calls more frequently at bucks like Ryan said, mature bucks that have passed or are not coming toward me. I will also blind wheeze calls more often this time of year as well. I have called in several mature bucks and either killed or missed some of them.
I don't rattle much during primary rut. I've found that young bucks will come into rattling, but mature bucks are rare. BUT... I do use the rattling of what I call Puppet Fights during late season. This is after Christmas. I tie 4 large shed antlers together and let them lay on the ground while in a tree stand with a long haul-line. The line is used to lift and swing the antlers and rattle together, crashing against brush, leaves, tree trunk. I do this with one hand and bow with nocked arrow in other. This time of year, there is an increase in buck to receptive doe ratio. This creates great competition, and mature bucks tend to get involve. I have an entire chapter in my book. I have killed mature bucks using this method, as you are the puppet master and can create soft rattle and control intensity of fight. The idea is to turn the bucks as they begin to circle downwind with use of sound. The sound is directed from the ground level as opposed to elevation. This is important as bucks close in.
I still use tarsal glands from deer Ive killed as lure. Save and freeze in ziplock bags and use and re-use as needed. I hang near close by scrape while in tree while hunting, relative to wind. This helps raise curiosity of deer as they start to pass by me in tree. .... and the idea is you are using the scent of deer that lived in that same woods or area. I put a zip tie loop through the hock skin to make ease of hanging. Wear gloves. Mike
