I know it is just a few hours after New Years Eve but that is not the head I am referring to!
I am talking about the head of a tennis racquet. I received a couple of racquets for some work and I was immediately taken by the great distortion of one of the racquets.
I think it is easy to see which head shape is the right shape! The head on the left is .210 inches narrower than the head on the right. That is a lot! Way too much, in fact.
The tension on the stringers tag is 52/54. Why? The string is some sort of polyester, and the SBS data are;
ERT1000 = 33
RDC = 48
FlexFour = 64
These data are included only so I can compare to future data. The string is used so this is not intended to correspond the tension setting of 52/54.
A racquet that is distorted to this extent is not performing as it is designed to perform! A racquet should be the same shape after stringing than before stringing even though it goes through some changes during the installation process.
Take care of your head!
