Damn... that coon has definitely been caught and was able to break free or saw one of his buddies get caught. He knows the mechanics of this trap. I agree; you need something new that he is not familiar with.
I've learned for myself, though, that no matter what, they just keep coming, and it's a never-ending, tiring battle. Next year, I am going to focus on prevention.
Have you thought about installing an electric fence around your trees? Something like this:

Culo, ha?
Nice touch... but it should be culi, really. Molti culi.
A couple of thoughts after watching your highly entertaining video once again.
I am surprised that neither of the two coons entered the cage, but one did yesterday. I am also surprised that the skunk also didn't enter the cage. Yeah, I know, you mentioned that they don't climb. But I've seen them climb my 15g pots and steal figs hanging up to 20 inches off the ground. They also climb my retaining walls and get on top of my 20" tall wooden containers. The one in your video is also a bit of a climber.
So, they all went straight to the back of the trap. I think that's because the smell was very strong from that end of the cage and there was nothing attractive on the other side. You need to experiment with placing a trail of small treats starting in front of the cage opening and leading all the way to the back where you'd have a big 'prize' treat. Perhaps that is the key to success - they will lose their guard while getting easy treats and nothing bad happening to them and become careless enough to step on the trip plate.
