Glazing is the main key here, as for calling I pretty much let the elk decide on how much I call to them. If they seem to be rutting hard then just about any call will work as long it sounds some what like an elk. Just remember elk make a lot of different sounds and a lot of the calls you see on the market make too perfect sounds. Learn to different calls making different type of sounds. I find myself sitting and listening to elk a lot if I can't find away to get in on them. I also carry at least 2 different bugles with me and at least 3 different cow calls with me along with my favorite call is the mouth diaphragm calls. Now this is just based off my own personal experience that works for me, so you might try some of this stuff and make some of your own.
