this is a subject that is being beat to death on the forum. in spite of that, i feel the need to get an integrated view. pro stock Head racquets are easily identified. other brands are not. for some high profile players, dunlop and yonex will include the player's name in the pj. my questions are: how do the pro stock frames differ from their retail analogs? ... and how does one differentiate/authenticate the pro stock versus retail? ... are some frames of pros simply retail frames selected for post-production customization by racquet techs such as priority one?
