Title: Get the large one
Review: All I can say is that the small size was quickly outgrown. He still bats at it, and if I get it spinning for him he'll play with it for a long time, but at a friend's house he played with the large size and it was much, much more fun. This is a cool toy, and I love the way it's thoughtfully designed to make the ball wiggle a bit before it stops, but get the large!
