this might just be a small thing but i thought i should ask it anyways in case. on a two-handed backhand, i noticed that the pros put both hands not exactly squashed together, but theres at least a finger or two's worth of space between one hand and the other. and they put their hands above the butt cap part of the grip, which sticks out. For my backhand, my coach once said that if i put my hands more together, i'd get more power, and i also put my hands pretty low on the grip, but almost all these pros i see, don't really do that. is it better to have your hands a little spread out, and higher up on the grip? i'm not trying to exaggerate any of this, so think tiny.
