They are all surviving, with maybe only a couple making money. There is too much saturation of balls and not enough people in bowling like there once was.
This why the international market is helping a lot of them survive. Especially the small companies. It's expensive to run a ball plant, you have to sell a lot of balls to make good money, when there is so many choices for the consumer that has dwindled down anyway, something has to give or you keep on keeping on and try to "make a living".
