I received my latest "used" Prince Classic Response 97 from the TW used racket section. I find no evidence that this racket has ever even been handled, not one scratch, smudge or whatever. The grip looks "ungripped." Even though I requested "unstrung" it came strung with a shaped poly that not one speck of green fuzz was caught in the intersections. Also, not even the slightest indication of notching. I'll use those strings just for the fun of it.
I still think the racket, as others have said, can use some lead at 12 o'clock.
