Lane Bed: Score wars. Boy isn't that the truth. I have 4 centers within a half hour of where I live to the north, west and south of me. Three of the houses put out shots that elevate bowlers to 220-230 average status with no problem, and 1 house where the owner doesn't have a clue what to put out there and you are lucky to have a 600 series.
To answer Pinbuster's question, I think the new balls come out to battle the new lane conditions. Every time more oil is put out front, you can count on a new flood ball that will store all its energy for the drier back ends, wherever they may start in a particular house. I also agree that I've seen many people in my local houses buy the latest hook monster from their favorite company of choice, only to be disappointed as the ball takes out the corner pin or hits super flat because there isn't enough oil for the conditions they bowl on to properly use the ball for its primary purpose. Since I rarely see floods, I find the need for a hook monster only when I see them, which tends to be once or twice a year...
