I have read all the debates, seen all the arguments and watched all the tapes even since the rec.sport.billiard days. The experts say no difference, or it isn't measurable.
I disagree. I can't prove it, nor measure it. But from my personal experience I can get more spin on the ball with a freshly installed Elkmaster than with a Triangle that has been fully broken in. It's not placebo effect. It's not me doing anything different. I've done this on the same cue, same shaft.
I don't know if it is because the softer tip stays on the ball longer, or if it just grips it better during the same duration of contact. No idea. I don't even care. I just go by the results. I was a skeptic of my own observations for 20 years. I can't sit back and believe the "science" of it when it runs contrary to my personal observation. Can't do it anymore. I think certain ideas that are prevailing ought to be challenged.
It s simple. Imagine that you hit cb on the same spot and same power, with soft and hard tip.
Cb will have same ammount of spin in both hits, but with softer tip CB will travel slower,
so ball will have more revolution per distance.
