I used to do road course race car tracking. I have instructed at over 120 track days. Constantly I encountered students (and others) whose primary focus was on the car: what mods should I make? Should I get (these brake pads) (these shocks) (this exhaust) (these sway bars)? My usual answer was "make the nut that holds the steering wheel as good as the car, then start improving the car."
I am also a HPDE driving instructor. We have a saying--do you know the fastest way to slow a driver down? Yes, add 100 HP to his car.
Similar to those questions, but not being particularly experienced with a wide variety of cue sticks, my question: When (or ever?) should someone interested in improving his or her game, invest in a "good" cue? How do we know when our equipment is holding us back?
The corollary to the HPDE above is::
If you cannot run 3 racks with a $60 cue, with which you have had plenty of practice time, higher dollar cures will not improve your game.
