I've been playing with this very low end racket for the past few years, and I recently upgraded. But, I'd like to see what are the major differences between the two rackets The Carbonex 7000 was from Costco I think, so I don't know the full specs of it The tension is 16-20, and Grip is 5. Weight is 2U I bought this racket. http://www.badmintonbay.com/product_info.php?cPath=28_42&products_id=144 What are the main differences that I will be noticing with the new racket compared to the old one?
