This has always bugged me. With pool cues, people stress over deflection making the cue inaccurate, hard to control. Deflection is based on tip end mass. The heavier the tip end of the shaft is in comparison to the cue ball's mass, the more deflection the cue will have. Pool balls are significantly more massive than snooker balls, and brass is significantly more dense than wood or even the plastics we use in pool cue ferrules. However, snooker cues have heavy brass ferrules & are used to drive smaller, less massive balls. Logic would dictate that a snooker cue with brass ferrule couldn't possibly be used to accurately play the game, yet it's done so regularly and on tables with tiny pockets barely large enough to fit a single ball. Our pool tables are considered tight if two balls just fit. Am I the only one who has always noticed this irony?
Could it be that deflection, however scientifically factual it may be, plays tremendously less role in cue accuracy than folks think it does? I know that's off topic, just thinking out loud.
