Easton makes a pretty cool looking small game head that comes in the deep six thread configuration. It is not exactly a judo point, but may work for you depending on your needs.
I have seen it. Judo's head lends itself to two things. One the springs prevent burying in foliage. Two the round section aft forward lend tree removal. No rival. Thank you though.
It looks like overkill for a small game head, plus the cost for something that you will likely shoot into a rock. I love the original Judo tip and always Cary at least one with me.
