Thanks for the pics North40. Factual, respectful debate is what makes us learn and solve problems, so I'm all for it. North40, when you get a chance, set both traps and lay them side by side and take a pic. The MB does not have a loose jaw when set, the K9 does. The elongated pan on the K9 allows the trap to be triggered with the coyotes paw still partially out of the trap, this results in a certain percentage of misses. The MB's pan is smaller and centered in the trap. If a coyote steps on the pan his whole pad is within the jaws. High volume trapping is a game of percentages and everything you can do to tweek your eqpt. ups those percentages.
