In Washington Heights we used the Spaldeens… don’t remember the pinkys which, based on the discussion here, sound like basically the same sort of ball. We did have a Pink ball that was made of a different material than the spaldeen… it was a foam rubber ball… heavier, lots of bounce, but the grip of the soft rubber foam on the ground made it have “unpredictable” bouncing behaviors. We didn’t use those much, I don’t think, we used the spaldeens. Anyone else remember the Pink foam rubber balls I am refering to?
