After 3 or 4 years of baseline singles I have started to learn to serve and volley, after about 6 months I've learned that there's a lot to learn and I have improved a great deal and I'm still improving, but I'm not nearly as good with it as with my baseline game. That's to be expected I guess, but the problem is that in order to get better at it I have to practice it and not just in practice but in matches too. That means losing some points/games/sets or even matches that I might otherwise be able to win. How/when do you decide that a style of play is really for you or not? How much time do give an experiment before you declare it a failure? How do you decide if something will be full time style of play, or a situational strategy, or something in between?
