For those of us who live north of the equator, it won't be long before the weather forces many of us indoors. My belief is that any fast or medium fast surface lends itself to the serve and volley approach to tennis . However, serving and volleying can be successful on slower surfaces, as evidenced by Patrick Rafter's superlative play during the 1999 European clay tournaments. Our bodies just can't handle the beating that a backcourt game inflicts when we compete on hardcourts. If you live in the USA, chances are that you play many if not most of your matches on these surfaces.
Juniors can benefit from learning to serve and volley.
Most juniors and college players are great backcourt players with well-developed groundstrokes. But, I have never seen a junior player beat one who is accomplished at serving and volleying. I truly believe that the junior or college player who can serve and volley with proficiency will prevail in most matches. Most juniors and college players are not used to seeing opponents rushing the net. They simply don't know how to defend against this attacking style of play.
