Everyone here rants on and on about how pros don't use the racket they advertise. However, many new technologies have some physical difference that cannnot be made with paint: TCS ridges of LM, the rounded throat of Williams nCodes, O-Ports on O3, V shape on VE, and more, I'm sure. These looks cannot be mimiced. Thus, the pros seen with these rackets must be using them in reality. Also, do pros regularly demo new models of rackets at all? If not, they could be hurting themselves. I understand "if it ain't broke, don't fix it." However, I personally am glad medical professionals don't follow this methodology because then we would never get new and better medicines if doctors never ventured to risk prescribing new medications. Some new racket technologies may have benefits to some pros, and they may be missing out if they don't try some of them out. I know I have played with a racket and loved it, but then tried a new one and it was almost exactly the same only better. So if a pro could demo a similar racket to what they like, only it has a new quality that makes it better, his/her game could legitimately improve. Just a couple of things that have been kind of bothering me lately.
