A graphite cue has a chance to be engineered for less squirt. Whether it is or not, you have to learn to measure for yourself. The player who has proper cue movement will adjust quicker. But if a cue has a lot of squirt, the compensation becomes very difficult. You focus on the cue while I focus on the student.
Cues vary by more than a factor of four for how much squirt they have.
Joseph Mejia and I were the editors. The manual is on how to teach, not how to play. No book or video can compare to personal instruction. If you have sound mechanics, then a better cue will make for a better game. I admit that's a big IF though.
