Wrong, apples to oranges, but if you really played pool you'd know that, sorry for correcting you, but you ARE wrong.
Let me give you just one example of you being wrong. If you take the cue ball and shoot it the cull length of the table dead down the middle and contact the center diamond on the foot rail with either extreme 9 or 3 o'clock english/spin, you'll be able to come off the cushion at a greater angle rebounding off the Artemis cushions than you ever will coming off the superspeed cushions, why is that? Try shortening up a bank shot on the klematch P59 K55 profile cushions, good luck. Why do you think billiards cushions are so dense, so hard, in fact so hard that if you stretch the rail cloth with a pair of pliers and place a staple right next to the nose of the pliers, the nose of the cushions won't show any signs of dimpling? No, superspeed cushions don't play anywhere near what Artemis or Klematch cushions, for pool, they play better period.
If I really played pool? LOL
Dude you need to stop talking out of the side of your face.
Sorry but they all make "good" pool cushions regardless of your opinion.
Furthermore, without any proof of your claims, its just a bunch of hot air.
"I'm the great and powerful Glen and nobody knows more about rubber than ME!
...Or rails!
..Or tables!
...Or cloth!
I am The Glen and you are all IDIOTS ! "
Please show us the results of your durometer tests Glen.
(ANY durometer testing you have done to Brunswick, Artemis or Klematch cushions)
Show us the video(s) of identical tables set up with different cushions for testing.
Show us the ramp you've built for launching balls into various cushions at the exact same speed and angle.
Show us the chemical makeup comparison of each cushion and their % of gum rubber + additives.
After you do, then we can have a serious conversation about cushions.
