You're right -- according to him.
I think what we have here are competitors making competing claims. I suppose an independent lab test would help but I doubt that's going to happen.
One thing I do know from personal experience, comparing a new set of Aramiths to a new set of Cyclop balls, is that the Cyclop balls stay cleaner waaaaay longer. I've been told, by PS at Diamond, that is because of the higher phenolic resin content that makes the Cyclop balls harder and able to be polished to a smoother finish. YMMV.
Just as a general comment: being able to adjust to different equipment is a skill in and of itself. Some tournaments and pool halls use Aramiths and/or Centennials. At many pool halls these balls have miles and miles on them and there is often a pygmy CB to add to the fun. More and more pool halls are using Cyclop to go with their Diamond tables. Other times you have to adjust to a measles v a red circle CB. At one major venue in the midwest, players are shuttled from GCs to a Diamond table, from tournament round to tournament round.
Sooooo, like I said, good players learn to adjust regardless of their preferences. I own several sets of balls and have come to peace with all of them. It's the price of being out in the world. OTOH, if you're just going to play in your basement all the time, certainly you should use whatever you prefer. Overall, I think that sometimes -- when people complain about one set of balls or another -- I wonder whether they ever get out into the world. I've played in tournaments where the entire set of balls don't match -- management having replaced stolen 8balls and/or 9balls with spares from other sets that obviously don't match; red circle CBs that are so small and old they should be called pink circles; on tables that roll off or have gaffe pockets or tons of tears in them or a dead rail or two.
But oh my, gosh me! God forbid they don't like the colors of a certain set or the way a particular CB plays, lol.
The translucency of the original Cyclop CB was part of an effort to make the CB more distinguishable to the Diamond Smart Table optical density sensor. And yes, the ball played differently than a red circle, which plays different from a measles CB. Now there is the Cyclop red dot which is better matched and plays very near a red circle. You should try it. Manufacturers are usually trying to improve their product. GCs went from the GC1 to the GC5. Diamond went from the Red label to the Blue label and even Blue labels will have changes in the future.
Look at all the generations shaft makers have gone through, and for that matter, pool cue makers in general. Over the course of time they learn things about their product and player preferences. As to the opinion of pros, take a look at tournament results. The same guys seem to do fine with the Cyclop balls.
