True but to a degree.
After a while, you kind of know what you like in a pool cue, like weight and balance and shaft stiffness and tip hardness.
And you will play better with such a cue.
I know what I like to play with, at least I know what I liked 15 years ago before I stopped playing.
Trying to pick it up again in the past 6 months, showed me that what I liked 15 years ago, doesn’t work that great for me today.
I’ve been mixing and matching butts and shafts in my collection to find what works best for me today and honestly, I’m quite surprised with the combination that works best for right now.
