Hello Danny D,
It is, 03 as you said. Ivory ferrules are not a rip off.
Some like them, some, don't. It's that simple.
Ivory deflects more, not in my opinion, sir.
I have played with many with differant kinds of ferrules, checking out this very subject.
Ivory has the most "life", and allows the ball to leave the tip faster and cleaner, than the others.
Ivory ferrules have more "life" in them than the fiber and or plastic ones.
When you hit the cue ball, the ball bounces off the tip several times. [an average of 3 to 4 times per hit with plastic ferrules]. With ivory it's less, bouncing. It 's [2 to 3 times].
I watched this on slow motion film, about 20 years ago. By bouncing less, the cue ball will travel closer to it's intended contact point. Another words it's squrits less. With ivory, the ball gets away from the tip faster.
Mr. Buddy Hall, who at one time was considered the best 9 ballers, used them with my cues for years, Danny DiLiberto, Jimmy Matya, Wade Crane, Buddy Dennis, Mizerak, Jimmy Fusco, Grady, and many more. These folks just perfered ivory over the other choices.
No question about it, you do have to adjust playing with ivory, as you do when you switch to something else.[small learning curve]
Choice, that's what it's all about, choice. Some drive fords , chevys, caddys, and so on.
