This is the best ball I have played with. Comparing to the Joola Plastic balls which I broke around 8/9. I haven't broke any of these. Around 60% of my club use this balls now after a lot of people moved to plastic balls. This are much more durable, especially at smashing. They are not very light which means you get more power but still a bit less than with the celluloid balls. Any questions just ask.
