I think the game has evolved and it is silly to try and "standardize" equipment so that people can hit with better technique. Regardless of who is playing, the ones with the best technique will be the best over those who have the same equipment with poor technique. The only thing that can come from using a wood racquet and 18X20 string pattern is the same old game. When everyone uses new technology the game evolves (whether you think that is good or bad) at an equal level from the club player up to the pro's; the best technique will always prevail regardless of the technology!
