People/Manufacturers sometimes use lead tape on the wood handle of a badminton racquet to obtained 'desired' weight/balance. Here is an argument (http://en.wikipedia.org/wiki/Argument) to suggest that lead tape is virtualy as useful as putting extra rings on your playing hand: Consider 'the system' as your arm, wrist, hand and racquet. The racquet's handle has x grams of lead tape underneath the grip - This is the normal configuration. Ignoring the comfort factor and coefficient of friction of the lead tape etc etc, considering ONLY the effect of the lead tape on the balance and weight of the racket: Propositions: There is no difference having the lead tape underneath or on top of the grip. There is no difference to having the lead tape attached to the hand or the grip, as long as it meets hand and grip in the same fashion By choosing a suitable weight and placement of lead tape, it is possible to replace the lead tape (with e.g. finger rings), such that the weight and balance of 'the system' is unchanged. Conclusion 1: Applying lead tape can be equivalent to adding finger rings. We now have reached the point where proponents of lead tape MUST ACCEPT that adding weight to you hand/fingers (ie something external to the racquet) has the same effect (or else they must point out some problem with the proposition and conclusion). Prop A: people add lead tape because it changes the (feel of the) head-heaviness of the racquet. conclusion 2: If prop. A is true, and prop. 1-3 are true, the (feel of the) head-heaviness of the racket can be altered without touching the racquet at all! "In before": Q: But if you put rings on your hand, your hand moves when you change grip, therefore it cant be the same. A: Only consider one grip where it is the same - the logic will follow through Q: placing the lead tape on outside of the grip moves it further awayf from the shaft axis so it does affect the balance of the system. A: Two points to this. One: The balance difference is orthogonal to the longitudinal direction we are interested in. Two: The difference between over/under grip is minimal anyway. Discuss.
