FYI, I just dug out my old Wilson Sting 85 strung with Prince Synth 16g 20 yrs ago; it weighs 12.41 oz and I bounced a tennis ball on its old string and it still gives me the good old box beam feel. It has the same design with an arch cross bar at the throat. The box beam is 17.5mm. I also have the 110 version which is 18mm; weighs 11.9oz without the leather grip (12.9oz with leather grip). I loved these rackets but only wished Wilson made a 95 in the thin beam design; they did make a wide beam later on but it's not the same thin box beam.Oh oops my bad then. Does the classic graphite really weigh 12.9 oz strung?
