Because saying how you played since 25 years give you the correct knowledge to judge if a racket is less powerful than another one without testing it and only by watching a match on TV? Did you ever hold the racket? No you are just saying (and not just saying you use strong words like "noticeably weaker") many things about it just by watching a match on your couch? Ok that's pretty credible and not arrogant at all actually. Also please don't just say words out of context. I never assumed users on the forum including you and Quentin 11 do not play and only stay on the couch... Obviously the staying on the couch thing was for the 100ZZ thing racket feedback you gave out of nowhere... nothing else. If you start reviewing your racket, regardless of your feelings I won't say that but again you never tried that 100ZZ yet have plenty of assumptions made. Don't take my words out of the context to discredit me. Again... Ah yeah I'm also arguing with all the members on here right. And I'm arrogant right. And why? Because I question how you guys stated so many things without trying the actual racket? Sure... And since you guys never answered my question and don't have any arguments other than attacking me or throwing some nonsense about the meaning of "impression" or how I assume you are sitting on the couch reporting the qualities of a racket you never tried (spot on actually right?!) when I ask how can you tell (and so surely) that the 100ZZ is less powerful than the DZS based on TV matches you watched sitting on your couch... well then I will just leave it at that. I'm that arrogant and surely I didn't read correctly the both of you. I have other users to argue with anyway. In fact "all the members".
