...#1 check your trapping regulations because many states have a trap width restriction on footholds. that will determine what size you need. I echo what Matt B said about Bridgers. I have used MB550's and Bridgers but I can nightlatch the Bridgers to my liking...more on that later....but they are reasonable and very reliable. IF you're trapping yotes, I use a #2 Bridger offset, 4 coil. with 4 springs on it. They are built strong, have a welded chain and two inline swivels....just received 6 more new ones the other day...look for tracks and scat....go online to youtube and you can view videos of how to make a dirthole, flat and scent pole sets...I attach a j-hook to the end of the swivel, add a Paws shock spring to that and use a quick link to hook the other end of the shock spring to a 15" duckbill cable stake.....I used to use rebar, but no more. the hooks crimp easily with a big pair of vise grips.
