Hey, I have two Prostaff 6.0 Original 85s- however I can't figure out where they were made. I can't find any reference that shows the location where the racket was made according to code, and I don't really know how to compare the different locations by paint type, etc. The code on the buttcaps of both of these rackets is GHX. I'm hoping someone has these codes down for one of the specific 6.0 locations. Any help is appreciated. Thanks!
