I picked one up from Jeff Carter last year. The first time i used it (after some fitting adjustments)I shot 300 in a practice session. I threw 19 in a row before i left a 10 to stop it. It was on a pair that had the nights league games on it without being reran. It is a great ball for lanes when they are broken down a bit. As Jeff always say's "Bowl up a Storm".
