Used Tecnifibre 320 16/20 cosmetic condition about 7 out of 10. This is the hard to find 16/20 string pattern version before VO2 Max. Frame has no cracks and plays like new. The grip was autographed by Fernando Verdasco at the CountryWide Classic in LA two summers ago. $80 shipped. E-mail me at firstname.lastname@example.org. Thanks.
