I have three kind of Yonex AT 700 ( old model ( black ), new model ( red ) and limited ) and I feel there were little difference. The old AT 700 I think the most balance among AT 700. It was great for offensive playing The new AT 700 ( red ) I think the worse among AT 700. It feels very heavy, very stiff ( not flexible ). I feel tired using this racquet, and made me slow. The AT 700 Limited was the most offensive, It feels heaviest among AT 700 but not stiff as New 700. It feels very great when using for smash, drop shot and need little power to hit shuttle cock I hope this will help you.
