If Llodra and F. Lopez can serve-volley well, others (with even more athleticism and raw talent) could too. Tennis styles move in cycles like everything else including nature. All it will take is some as yet unknown MEGA star to change our perceptions again!
The current scene is alienating potential fans (even me!) that just cannot sit through 2 to 5 hours of the same rally repeated ad nauseam 200 times, hence miniscule TV ratings (well below a .5 share) and 2/3 empty stadia at many late round ATP/WTA tour events. At least the women have widely varying results: e.g. a Kvitova could win a Slam or lose 1st round; Serena could get ill or injured etc.
