I have 3 rackets A Prince O3 Blue (26kg)
Prince White O3 ( yes also my competetive racket) (25.5 kg)
Babolat NS Drive (25.5 kg)
I have a Monarch with the old type of nylon strings, and a narrow head. The width of the head and the length of the racquet add up to 666 mm which is the height of the net for men's tennis. Women's is higher I believe to make the game easier.
