Recently at the Tennis on Campus Championships there was a guy hawking these racquets and offering preferred player packages at $225 for 2 racquets and a bag. He said the racquets were a blend between the pure drive and K-factor racquets. However he didn't even know specs of weight or balance. Anyone on here heard of these racquets before? The pics he had in his flyer handout didn't look like anything impressive.... I'm thinking about trying a demo what do you all think?
