Hmm, it's possible. Didn't they distribute the materials differently this time? The NF700 certainly has incredible feel for a light racket, and I chalked that up to materials. It would make sense that it's too stiff at the top of the racket if that's the case; most rackets flex a little during stringing, especially towards the top. If it's inflexible, it'll be more brittle. The 700 had softer sections on the top left and right, with the harder material at 12 o'clock. I've gotta say, I'm not a big fan of the stringing pattern on the NF700. I prefer either the 4+2 pattern, or 72 hole pattern. I'm not a fan of the 3+2 with a big gap at the top (and some LN rackets do this too).
