I just obtained 2 older raquets, and wanted to see if anyone knew anything about them. 1) ESTUSA XDH TURBO.It has a combination of Kevlar Boron Graphite. It has a black frame with some gold stripes. 2) ESTUSA XET CHARGER. It has Kevlar and Graphite. It is black with some silver and blue stripes. Any information would greatly be appreciated.
