Is it fair to say that : 1) The half volley is an advanced shot? 2) There are few opportunities for the average 3.5 player who is on the court 2 hours per week to practice this. 3) You can play tennis successfully at the 3.5 level without ever using this shot. 4) It is a risky shot if you are not very confident in seeing exactly where the ball will land. There is limited time for practicing, trying to sort out where to best use my time since I can't work on the 40 - 50 skills that someone with all the time in the world and good practice partners can work on. Thanks for your feedback.
