The CC7 blade is a more powerful blade than the CC5. This blade is recommended for highly skilled attackers with excel- lent technique. The CC7 blade is outstanding when you are playing back off the table and getting into topspin rallies. With this blade you can feel the long trajectory in your topspin strokes and gain control over the game. If you like to play top- spin against topspin, then this is the blade for you.
