I like simple blunts and Ace Hexblunts the best. I used to judos until I actually started killing alot of things, LOL. I find that judos make a mess of small game when they penetrate. They pull hair and dirt into and through the wound channel, making it much harder to clean, especially rabbits.
I also feel that the spring arms may dissipate energy that a blunt would transfer directly to the animal. I have had hits on rabbits and squirrels with judos, where it nocked them for a loop without penetration, but it didnt kill 'em. I have done the same thing with blunts, and the animal died from the shock of the hit, even if there was no penetration.
