Although the dribble below could be written off as complete ignorance, it does actually highlight a real problem with the drastic assault on the spirit and character of tennis.
Using poly strings in oversized racquets actually goes against the spirit of tennis. The text below is from the official rules of tennis, in relation to spaghetti string jobs and string savers that gripped the ball .. and completely relevant to poly:
The spirit of this rule is to prevent undue spin on the ball that would result in a change in the character of the game. The stringing must be made so that the moves between the strings will not exceed what is possible for instance with 18 mains and 18 crosses uniformly spaced and interlaced in a stringing area of 75 square inches (484 sq. cm).
What is being discussed above is indeed the result of undue spin changing the character of the game.
