Im no expert on bobcats but in my limited experience, they are the least interested in lures of the predators. You have to be on location OR have a good flashy set to attract them. Then the lure should interest them long enough to stick their nose in it and step on your pan.
Their behavior is different from a dog or other predators. Its possible to draw them in from long distances with a feather on a string blowing in the wind over your set, or have a bunch of feathers scattered around your set. Ive watched them ignore awesome sets with lure/bait, but caught them on stupid sets with no bait that was in the right spot. Use their curiosity against them. A set that is easy and quick to investigate will catch less than sets that require more time and work for them to figure out. A pile of brush, haybale, hay pile, farm junkpile, that type of flashy set will require more investigation than a dirthole set with fancy lure. Use your trail cams to observe them at your sets. Set along trails/habitat where you have gotten trail cam pix. I know it didn't answer your lure question but hope this helps. Go get em !
