Update 5-30-02:
After more usage, I felt that the ball started hooking a bit too early, leaving very little pop on the back end. I had it polished up, and it's a much better reaction. It's drilled label leverage, so it ain't much use inside, but that's not why I bought it. I've also quit using it for spares - there's too much variation from house to house, and there are some conditions where it's too much ball for right side spares. It's still a great control ball - good combination of mild shell and core.

This rating is for a Beast with Mica LTD (regular - not pearl). It's the same as the currently sold Mica Beast except that it has a little bit more mica in the coverstock. I don't think it makes any difference at all. Very mild and controllable ball. Not much more aggressive than a urethane. I'd been using a Faball Berry Razor as my "go to" ball when the lanes were on the dry side or I just needed to get the ball farther down the lane. The Beast starts rolling a few feet earlier but doesn't move as much. A much smoother arc than the Razor. This will be an excellent ball for screaming back ends, or along the edge of a wet-dry wall. Where does it fit? With the Beast I have to stand about 5 boards farther right compared to my Columbia Spirit, and it moves a few boards more than a urethane Black Angle. This little Beastie is going to do double duty in my arsenal- dry lane AND all-purpose spare ball. It's going to replace my white-dot for those right side spares. Because it's mild it doesn't want to hook past those 10 pins, and since it's not a hard plastic it will hang on the edge should you happen to miss right by a board or two. I love it! One small oddity, after drilling the thumbhole I found little pits and voids in the interior. Perhaps the extra load of Mica affected the consistency of the coverstock? Who knows. The ball looks all right on the outside and hasn't cracked into pieces yet J.
