Recently I've been having a bit of trouble. It's been windy lately, so lobs are getting hard to time well. However, I usually can't decide which one to use when the other guy gets to the net. Certainly the passing shot is much more effective, but the lob usually drains the person's stamina as they run backwards to get it (although few can return it if it goes over their head). It also demoralizes them to realize they tried so hard and met with little sucess. I suppose this question is more of a "safe shot for points" or "ugly shot" for physical and mental deterioration.
