If you're talking overall hook, it's very possible that the Animal would win out simply because the Animal is particle whereas the KISanded is a resin ball. From the Animals i've seen and the KISandeds i've seen, i've found that the Animal is more rolly whereas the KISanded isn't really a skid/flip, but it's not really rolly either...somewhere in between I suppose. For what it's worth, i've only seen no more than 5-10 people throwing each ball, so i'd HARDLY be considered an expert, just adding my two cents.
