I wouldnt say im the man hear, and Rob who obviously has a ton of experience as well as many others could probably give more details but... Knowing what kind of stance the deer is in seems to be the biggest issue. If its a buck feeding out in a field in mid september, the likeliness that an aggressive call/snort wheeze is going to work is probably slim to none. Now, when its late october/early november and you have rattled him in, but dont want him to pin point your sound and he seems to be loosing interest and isnt close enough to shoot, thats when i would go with an aggressive low/deep grunt or snort if you can do it...
About 4 years ago I rattled the biggest buck ive ever seen while hunitng run right to me... When he came in he was sooo alert it was ridiculous. I felt like I couldnt do anything else b/c i thought he owuld pin point my location. Another deep grunt and he came closer looking and into range. I failed on my part by missing him, but to say the least, he came to the calls.
Just my experience, which like i said is not necesarrily advanced, but ive set in the tree for a few hours in my 9yrs of bow hunting

Trial and error I guess really as ive not found something to work for every situation, but it seems like doing what you think the deer wants to hear is best.
How bout that video Rob???!!!
