There are different versions. The racket was in production for about 6 years, maybe 3 of those in China. The differences seem to be mostly cosmetic IMHO.
(Then there are the Czech ones.) The Chinese ones I have were pretty much dead on spec. There is going to be slight variations among all the various versions. That is the nature of any manufactured product especially one that was made in several different plants over 6 years. My favorite of my many PT's is probably a Designed In but that seems to be because I got the customization just right on that one. I think I probably have some of every version because I have so many of them. My take is that all the Pro Tours are great rackets and it is definitely one of my favorite rackets.
