So I'm in an organization that plays a lot of foosball. The table we have is a Tornado Cyclone II that's in decent shape. I've been working on improving the play quality of the table (leveling it, placing bricks inside to make it heavier, lubing it up, etc). But now I'm onto one of the more expensive part of the maintenance... buying new balls. So my question is what kind of balls should I buy and where should I buy them. I've only ever used Tornado tournament balls. I'm also not sure which generation play surface we have. Anyway, what we have now are some severely worn balls that let just about anything in if hit hard enough, and I'm trying to foster a sense that controlled play is more competitive than junk.
So yeah... which balls and where?
