I agree about the Infinate One. Mine never had much reaction and it has virtually none now. I call it The Rock, because I could be chucking a rock down there for all the reaction I get. Another bowler in my Wed league uses one and he's got no reaction either. They either got so oil soaked so fast or they were never much to start with, hard to tell. IMO, can't go wrong if you pick any other ball besides the Infinate One.
