Pretty good info. for sure, I would only add that one call I think is under utilized is lip squeaks. I am most definatly not a pro caller or anything close but alot of the coyotes I have called successfully have hung up at some point and put the stare on me. Moving to any kind of call would be the end of that hunt but lip squeaking can move them for a clean shot. You can get pretty loud with them too if you practice and the price is right for sure.
