When you ask Aramith about the difference between their Measle ball and their red dot, red circle, blue dot or blue circle balls they always say there is no difference. Not sure if something is getting lost in the Belgium to English translation or what..... The real questions is "Why offer more than one kind of Cue Ball?" Why is a red Circle ball even available if there is no difference? Why is the Pro Cup measle ball and the red circle ball a different color (yellowish) than their other balls?
There is a difference. The pro cup ball is heavier... buy one and weigh it. It's roughly 10 grams heavier and feels like it is made form a different polymer than the other Cue Balls. Just my opinion.
So if it seems different (other than just the color).... then it is. No matter who says what. Cyclop balls are made of a material that is very sticky. I can draw a Cyclop CB easier than I can other CB's.... even easier than a red Circle CB, which is easier to draw than a Red or blue dot. But nooooo, no difference there.
