Nails are the hardest thing. They have got thinner heads here in the last 15 years or so. The best I have found are menards 30d. I have a Jason Dufresne bender. It rocks. I also add a washer to my nail swivels. You can about spin the trap by blowing on it. Lol. Very easy. I’ve caugh hundreds of yotes with them and they have always performed flawlessly. I have had crunch proofs so plugged up with grassi doubt they worked. Also a giant pain in th butt to clean all that grass out of them.
If I thought there was a demand for it I would start making custom chain rigs when I retire.
Well I am retired kind of monkey doing my own but it ,,a guy have look at part and piece to see plus labor then shipping .
But put a sterling or something like it or jc conner rod dog on all new traps they bed way faster easier.
Beartooth trapper has got some of the long j-hooks I like also.
