I got this racket from a yard sale. After put in a new string and an overgrip, it plays so nice. I post on other thread and someone told me it plays like a pro stock PT5E but I am no expert on rackets. Can you help me with: 1. the spec of this racket. It is not on the racket. 2. with your expertise, which racket plays similar to this I.prestige MP. Thank You!
