do you guys think boiling traps and waxing is better than speed dip, if so how do you feel about speed dip. also is 8" of chain enough on traps for fox and coyote or do you need to add some? if so what should total length be with chain added? thanks

I boil wax/yote traps. Speed dip everything else.

Speed dip is not economical and less you're doing a few hundred traps imo. But you don't have to fool with traps every year.
