Where a stick balances on your finger is means nothing. I have an opinion on this matter that where you hold your cue is like the fulcrum there is a weight in front of your hand and behind. If a player only used a closed bridge and middle or low englishes there would be little or no need for forward weight(because your fingers are controling the tip at impact). But with an open bridge and topspin "like shooting over a ball" the only thing thats keeps the tip of the cue on the cue ball is the friction of the tip and the "downward" or forward weight. I have done experiments with lots of the production cues and think many of them are over engineered with too much forward weight (that way it covers the bulk of the buying public since you don't know where the fulcrum will be for an individual customer). A cue ball only weighs 6 to 6 1/4 ounces I have looked at many of the old threads and some of the high speed videos but they cover deflection with side spin a completely different subject than at what forward weight a cue stops skipping of a cueball. As "custom" cuemaker if you build say an 18 ounce cue what is your thoughts on the "correct" weight distribution for example 11 behind the hand 7 in front.
