I've used cat-man-do (Milligan) with a lot of success.
Again, my experience has been that variety is the spice of life. I try new stuff all the time. I keep a few sets around with my tried and true stuff...but honestly I think that there is so much dependence on the food available, population/competition of other species (and same species) that often those are the things that seem to make things "best" in any given year.
For instance, one year I had my best catches at sets baited with powder river paste bait, then the very next season I never got a set worked but I hammered coyotes on some bluegill and carp I'd caught that summer. If I would have stuck with only the powder river...would have been a mighty slim fur check that year.
Some years bait seems to be the ticket, other years they won't touch it but will find every post and flat set I put out.
I think the animal population, available other food sources (deer gut piles after season close, high bird and small game populations in area, cover and habitat, etc.) all play into the bait and lure game hugely. If I had the magical answers or forecast ability at onstart of each season, then I lose a lot of "fun" in the experimentation too. For me its not always about the check but the fun factor too.
One consistency I've found and stuck with is mix up your sets, mix up your lure/bait combos, and locations, too. I truly believe variety is the spice of life in predator trapping.
