Hard to find now, Wilson Pro Staff 6.0 Hyper Carbon Tour 90.  Used by none other than King of Tennis Roger Federer for awhile, I believe he won several slams using this frame.  Obviously suited for higher level player who can handle the heft, flex and smaller but lethal head size.  Needless to say ultimate playing control and feel, plus "power on demand" in the hands of an advanced player.  I call this racquet "the scalpel" because it is a surgeons tool on the tennis court, no weaknesses in performance for anyone over a NTRP 4.5 who plays with power.  Please ask any questions, always happy to help.We installed a brand new Wilson over grip, string OK to start playing with until you want to switch out to a higher level premium string.Specifications:Headsize: 90 square inchesLength: 27 inchesFlex RA: 68String Pattern: 16x19Weight: 12 ounces (340 grams)Balance: 11.9 HLMaterial: double braided hyber carbon graphitePlease ask any questions.Shipping is $14 in the US,  international shipping charges depend on country location and an additional $20 handling fee will always apply because I need to wait on a line, fill out customs forms, etc and I do not work for free.  Payment is due within 48 hours from close of auction sale, NO EXCEPTIONS.  I don't mind doing international shipping but please do not haggle with me about the shipping costs and the handling fee, if you don't want to pay that then you shouldn't be buying these type of tennis racquets where those fees will apply.  Thanks!
