You could have just used tennis fans. Would have been enough to get your point across.
most novak and rafa fans dont want faster surfaces (me excluded), guessing its similar with fans of clay court players, and "casual fans" who purely watch the sport on telly, ask them and they for sure wouldnt like all serve matches, thats boring and the reason why they slowed the courts in the first place. beside tennis appears to be at an all time high viewers-wise.
again, thats not to say the complaint in itself isnt right, it is, but whats popping up on forums such as MTF is in large measure an exaggeration coming from, lets call em, non rafa-djoko fans. I mean there is a tardish element in it, thats my impression.
