Re: Have a question about two-handed backhand?
You could allways try getting the same amount of power from both. In general I think most people would say the power comes from your non playing arm . If your going for lots of topspin , you need both pretty much equally . From how a coach taught me , you need to focus on turning your body as you hit it.
