I have viewed Nick Bolletteri's "Tenacious Net Play" and James Jensen's video on volleying. Both are OK. Nick's is more about footwork and postioning. James's does not go into much detail. I want a video that goes through the mechanics of hitting a volley. Where to strike the ball at what angle to get the desired results from various ball heights. I do serve and volley when playing, but I rely on the strength of my serve to get me weak put aways. I get into trouble when someone is not intimidated by a net rusher. thanks in advance.
