I wonder why most people dont follow the max stringing recommendation of Yonex. Most everyone will go up 2-3lbs more. And there are others that will go way overboard. Isnt there a research in Yonex saying, " The tension that they recommend is the optimum for a type of racquet. That a certain tension will give the highest level of Power and/or Control...any tension higher is just a waste" And if everyone strings racquets 2-3 lbs more, then shouldnt Yonex reinforce the racquets so much so that it will be safe to bring the string tension up.
