I've been thinking about and meaning to ask about this for a while now. As tennis players and tennis fans, it seems that we have so much more to take into account when we discuss strategies, match play, etc. than other sports. We have to consider wind speed, wind direction, surface, humidity, temperature, altitude, and much more. These factors affect not only the tennis ball, but also racquet strings. In my view, tennis has so many more outside factors outside of the control of the players than most, if not, all sports. Do you agree with tennis being so susceptible to outside conditions? If not, what changes do you think could be made to balls, racquets, etc. that lessen the impact of various conditions on matches?
