There's quite a bit of upper house bowlers who don't have spare balls or who's spare game leaves alot to be desired. I see so many guys hook it into single pins it's not even funny. Every night I see the 4, 7, 8 all get hooked into by righties, opposite for lefties. A ball such as a white dot takes that pattern out of the equation by throwing straight. I wonder how many of those 215 house bowlers still try to hook out for spares...
