First off, before you quit reading, this isn't a thread about whether I should use one or the other, nor is it about which of the two is better. Does having a 2HBH actually preserve stamina in your dominant hand? Let me describe, since I don't know how to really phrase my question. People use their dominant hand in tennis most of the time, all of the time if you have a 1HBH. You serve with your dominant hand, hit a forehand with it, volley with it and even backhand slice with it. Now, people who uses a 2HBH at least can conserve energy whenever they hit a backhand, since most of the energy comes from the non-dominant hand in a 2HBH. Therefore, they don't have to use one hand 100% of the time. Would a person with a 2HBH have an advantage over someone with a 1HBH in this manner? With all other things being equal? Or am I missing something pretty important in my deduction?
