I have a bunch of #3 dukes that work just fine for cats, gonna throw some mods on them and try them out for coyotes, I have never missed a cat in one, I am also not a professional trapper, but every cat I caught in them was caught way up high I do use a pretty stiff pan tension though. they may have a different tune, I am going to 4 coil and base plate them with some stronger chain.
