My impression is that the balls are getting better and better. When I had tried them one year ago my first reaction had been: I guess I have to quit. The ball had been like an egg (early Joola ball).

When i tested several balls in August they were much better and I liked Stiga and Tibhar the best (both are very similar).
So far I have played with Nittaku premium (which are by far the hardest), Nittaku normal, Donic, Stiga, Tibhar and Schildkrot. The difference is not that big anymore (except for the Nittaku premium ball). That said my choice is still the Stiga ball (I guess it is just because I like Stiga)
