unless you strip the racquets bare you cannot know for sure if there even is new material in them. i think the only difference is in the way they braid the graphite, but other than that...
some of the marketing claims are ridiculous IMO, like the thing they put in the throat of Head racquets that stiffens the racquet if it senses you need it for your next shot.
excuse me but that is straight from a James Bond movie
one thing i know though:in spite of all the changes and the aggressive marketing "bull bagels" i like my ncode six.one better than my blx six.one
ncode six.one tour 90
