Hello Herman,
I have always did 2-hand backhand volleys for so many years. I like your suggestions, like this one, you challenge me to try something I would not try otherwise (like this one hand backhand volley and buggy whip FH). Following your suggestion, I tried one-hand backhand volley this time! I am sometimes late but when I am not late, it looks better. I wish I learned one hand backhand volley when I learned volley first time! Anyways, I will keep on doing one hand backhand volley from now on whenever I have change to practice volley. All the other technique videos were very helpful. Thank you.
