Yeah, if ya want to piss off a coyote or coon, do what he said! OR better yet, use a good sharp broadhead so you kill them instead!
I've used the judo's for years and they simply work great for rabbit, prairie dog, grouse, dove, etc. They make finding your arrow easier because they won't just disappear under grass and weeds because those little springy arms will catch something and usually make the arrow stay on top of the vegetation. They are tough too, I've never seen one of those springy arms break off! If you use a field point, it just doesn't kill anything very effectively, and you'll loose more arrows than you have in your quiver!
