LB while I agree with most of what you are saying, You seem to emit the western aspect of calling with your hunting style. I know that is because it is where you hunt the most. Wider more open spaces where it is possible to see that coyote before he gets down wind of you. And without a doubt in my mind, it works for you...
Where I live, East Texas, if a coyote ran each time he smelled a human and "never stopped", he would wind up in the far west where you could magic mist him

/ubbthreads/images/graemlins/laugh.gif Just kidding.
This is an extremely populated area and all that one can do to minimize ones scent should be used. I say minimize the scent because that is all the suit is going to do.. It surley can't hide it but might keep it at a level to not make him turn inside out when he reaches down wind.
I don't own a scent lock suit because they cost to much and I don't think they are worth the money for varmint hunting.
I do however use scent neutralizers and have killed cooyotes in my neck of the woods (literally) at less than ten feet. Close enough for me to smell
them from downwind /ubbthreads/images/graemlins/wink.gif .
Dang near every shot that I get, is at less than 50 yards, as that is as far as you can see in most of the places that I hunt.
The best desciption that I could offer is sit in someones back yard with a wooden privacy fence and try to guess which side of the fence the coyote is going to jump over.
I remember at the hunt in Az. I saw more than a few coyotes turn and run like hell at over 500 yards when getting downwind of me.. Wish I'd had some of that magic mist along that time.
However when we switched to hunting more familiar type terrain(the pine woods) we called one into less than twenty yards. And my youngest boy nailed her.......James L.
BTW I been using that concoction long before I ever heard of you or even had a computer to access valuable information that comes with it from these boards. /ubbthreads/images/graemlins/wink.gif Information from such people as you that each one of these guys should listen to..
