Interesting, I have never really seen that before. Unfortunetly for the "Volley Doctor" there is more to volleys than just a firm wrist. Although I can see it helping certain aspects... To save 20 bucks couldn;t you just tie a string around your wrist and the handle of the racquet. Probably not as effective though.
In the end, I doubt it will hurt your volleys, you probably have nothing to lose. The best bet is to just hit an insane amount of volleys in practice and work them into your matches. Get some dubs in too, that will really help! it has made my volleys better.
I played singles last night and crushed some guy, I dominated the net. About 1/2 way through the beating he asked me if I ever considered playing dubs.
I always play dubs.
I do not know of anything better than what you said, time on the court. And you will have to be on the court to use the volley doctor anyways. I assume you could only use it in practice. I wouldn't want that thing strapped to my wrist when hitting other shots. So in the end you will be on the practice court with or without it.
Do you feel like you let the racquet head drop too much?
Anyone else seen anything that may help 10nut's volleys?
