use different lures at multiple sets? of course. I even use and recommend multiple lures at the SAME set.
I mix and match and don't pay a bit of attention to matching lures to the sets. Unless you are making a unlured trail set- whatever set you is not going to seem "natural" to a coyote. In other words- a manmade dirthole with manufactored scents or chemically prepared baits is not going to "imitate another canines food lair" or whatever. Same as a urine post set. Its not natural- its just a place to sniff and UNUSUAL odor- and then do what comes naturally. Canines pee on everything- esp stuff they find interesting, unusuall, threatening, on and on.
So any lured set- in my humble opinion of course- is a curisoity set- and thus any lure that is attrative to canines can be used at any set.
