Well now thaddeus, it doesn't get any more clear than that now does it. /ubbthreads/images/graemlins/confused.gif
Actually I use all three mentioned, you kinda have to if you hunt in different terrains.
If I have a natural barrier that I can get in front of (cliff, river, highway, etc.) I call into the wind.
If I have an open area with cover all around me, I make sure the wind is blowing to the open area.
If it's completely open, I'll go for the downwind and hope I can shoot farther then he can smell.
But then again, I'm certainly no expert.
Get another set of eyes to go with ya, or get an e-caller and position it crosswind about 30-40 yards away so the coyote is trying to wind it instead of you.
