New Seamless Plastic Poly Balls
I blogged about these on Dec. 26 (see second segment). There's been a lot of discussion online of these non-celluloid balls and how they'd change our sport. Here's my take.
First, a caveat. When I tested the newest poly ball at the Nationals, I was having arm problems at the time and so couldn't loop at full power, so perhaps my judgment on that is suspect. On the other hand, the top juniors who tried the ball out (four of them, all around 2300) thought it played pretty much the same as a regular ball. I wish I had a copy of the ball now so I could try it out again (with my arm mostly okay), along with others at my club.
At least one other person has tested the ball and posted he believes the ball (even the newest version) has less spin and speed. I'm suspicious that it's substantially different. I know the ball was the same size as a Nittaku, and had the same speed when I bounced them side by side, and seemed substantially the same when I hit with it, including the same weight, grippiness, etc. Serious question: what physical property would cause it to have less spin, and in particular, substantially less spin? Comments are welcome below.
But let's assume that the new ball does have less speed and spin, as some think. This might be true if, for example, the ball were bigger. (Though the slightly bigger ball I tested previously was actually faster than the current ball, though less spinny.)
