I am a complete novice in all things tennis, just coming to the sport (very) late in life. I have acquired a racquet I would ask your opinions on, if you don't mind: It's a Prince racquet, with the following markings... On the neck, it has 'Air', with an elongated 'O' shape after 'Air'. Following this it has 'Hybrid' above 'Blue' It has expanded holes at 12 and 6 o'clock 'Triple threat' markings (10 and 2 o'clock) 'Sweet spot expansion system' 9 and 3 o'clock. 'Midplus' at 6 o'clock 105" head size, 58 +/-5 lb string tension 275 gm (unstrung) wieght Is this a recognised racquet? Is it any good? I welcome your comments.
