IMO commercial baits/lures are over rated.
Keep doing what you are doing but experiment. Do 2 sets with meat/food scraps and no commercial lure/bait. If the commercial stuff outperforms, then trash my idea and go with what works.
In my experience, I get a LOT more rolling, digging, and skunks/coons in the sets with commercial bait/lure.
What seems to work best for me is some deer trimmings left to get just a little stinky in a ziplock bag, then put it in the freezer. When making your set, chop off a hunk near your set. Bait dirt hole. The residue of chopping makes a good extra scent lure and confidence builder for them to commit to working the dirt hole set.
