I'm guessing that there is a good reason that certain balls rack up a lot of reviews - namely that people see them perform well for a friend and decide to go out and get one themselves and the whole thing snowballs. The quality/ review quantity correlation may not be perfect, but I'm guessing it ain't too shabby.
What do you say guys? Could we have a list of the 10 most reviewed balls currently for sale - (not counting spareballs of course...)
