Would 10% butt, 50% shaft, 40% tip be reasonable?
I would say in all cases (with the exception of overall weight) butt 0%.
Joint 0%.
Then shaft/tip, depending on shot...
If dead center hit - shaft 1% / tip 1% (broom stick will do almost!)
Short shot with english - shaft 10% / tip 30%
Draw/follow - shaft 30% / tip 70%
Long shot with english - shaft 70% / tip 30%
Notes:
Weight of cue - Important to use weight you are used to. Also easier to shoot "delicate" shots with lighter weight cue.
Shaft - The shaft importance can be broken down into smoothness of shaft, taper, and deflection. I don't do well with a house cue shaft which is rough and sticky. Also note that some people have learned to shoot shots with english using a regular shaft and will do better with these, but others will do better with a low deflection shaft.
Tip - For dead center hit, does not matter much. For fast shots, medium or hard gets more speed. For english/draw/follow, a tip which has a good surface condition and an even coat of chalk works best and a player will be more consistent with their shots if they always use a tip in the same condition, same hardness, and same shape (nickel, dime). For least amount of cue ball deflection, a dime shaped tip is best.
Consistency - For consistency, it may not matter much which weight, which shaft, which tip, what hardness, what tip shape... But that the player *always* play with the same specification cue. We have all seen a player get a new cue and suddenly have trouble. Or get a new tip installed and suddenly have trouble. The problem is they are getting a DIFFERENT cue or a DIFFERENT tip!
