Personally I love the Sheer Havoc. Mine's drilled label and scuffed to 600, the reaction is absolutely phenomenal, so smooth and predictable! I've only seen about one or two others in my area (though alot of people, when seeing me throw it, have said "i've been thinking about getting that ball" to which my reply is "stop thinking, just get one!") Not entirely sure why this is, I don't think it was released at a bad time (it was along with the Untamed if I'm not mistaken, which is doing rather well.
