That is previous round of cloth and they went with simonis for this round. Hope to get mack again soon and will take a pic.The rail in the pic you just posted says "Gorina". I'm pretty sure that's not Simonis.
And what's up with the white mark on the red ball?
And tex is right, PBA balls. They have aramith too but nobody uses them.
I prefer the PBA balls. They seem a tad heavier and hold spin better than the aramith.
Never tried the dynaspheres.
