Using technology geared for the non-plastic 40mm ball, and the fact that these new plastic balls are accommodated by a temporary rule change till 2016 or longer, it's hard to give this an objective review. Since the ball is slightly bigger, it's going to be slower with less spin, just like there is less spin and speed with 38mm balls from 30mm, and also just like 40mm balls from 38mm balls. So here is what I can tell you about the new plastic ball...I begin my first test of the ball using my all-around Donic blade with very fast with spinny rubber, which is rated at 9.6 speed and 9.6 spin. The sound is different, I found it too slow for my paddle and rubber. Looping wasn't a problem because with the less spin, it was easier to attack, it took a little bit to adapt to how to spin the ball more effectively but still slower than the non-plastic balls. When I switched to an offensive blade, the difference of speed faded a bit. I didn't notice as much. I had no problem looping, chopping, and I did have better control with it. So I like it better with a faster blade along with my fast and spinny rubber. Since new technology geared for this ball is scarce and since this ball doesn't match the original specs as it remains a work in progress, I don't believe this is a game changer for the better or worse. This ball is not going to react as good for technology that wasn't meant for it, but I do believe it still worth playing with! :)
