Guys I am in India at the moment and have seen what is sold as a Wilson BLX Tour 90 but it weighs something like 11.2/11.3 oz. It doesn't have Federer's signature on the throat (I assume all Tour 90's being sold would do as he is currently their biggest marketing tool). Any thoughts? Is it a counterfeit racquet? If it's not counterfeit, what does it play like? Is it stable? I ask as I'd be tempted to buy it if any of you can vouch that it is stable. Also, I am currently in Calcutta, can any of you living here/who have visited the city recommend a place to buy racquets/gear (the shop I viewed the abovementioned racquet in is a chain called Body Line - can anyone recommend anywhere else to buy stuff at?). As always, thanks in advance who respond.
