So why do some players say X tip has more spin than Y tip?
In my experience, despite what many say or believe, a harder tip can produce a little more speed than a softer tip when the same effort is applied.
The extra speed allows spin to stay with the cb longer. This makes sense, physically, because a soft tip absorbs more of the impact (transfers less cue energy to the cb) when compared to a hard tip.
So the actual amount of spin generated between a hard tip and super soft tip might be very minor, but the difference in cb speed is definitely noticeable. Players tend to think there is more spin being applied, when actually it's a slight difference in cb speed.
I played with a hard tip for years (Talisman Pro), and when I switched to a super soft Kamui I found that I had to apply a little more effort (stroke speed) to get the same cb action on some shots.
Then I switched back to a hard tip for a while and had to dial back certain shots. For example, I'd be getting draw on long shots when I was just wanting a stop shot. I used to think it was because the hard tip produced more spin, but it's really just the slight increase in cb speed that allows the spin to stay with the ball longer.
I now use a super soft Zan tip, which after hitting a few hundred balls ends up really being a medium tip. Anyway, I like the way it feels, and that’s probably the most important factor when it comes to tip hardness - use whatever tip feels good/best.
