It seems to be more and more frequent occurance, clients whom you know are beginners or someone who is obviously lacking in strength and power in their game, come to you asking for 27/28/29/30lbs. not sure what they are thinking but i am guessing it is an ego thing. or the wrong conception that higher tension means more power. you know that once you are done with the racket, they will continue to hit like they did before, not too well, and even more so, you know that they will be able to get more repulsion from the string if they had chosen a lower tension. not to say a better longevity for the string and the racket. do you say a word to them? or just let it be?
