So like, how do you hold your mouse? I like to think that I hold it the most efficient way, but who knows.
I have by thumb on the side of the mouse, my index finger on the left mouse button, my middle finger on the scroll wheel, my ring finger on the right mouse button and my pinky finger on the side. This is particularly efficient when playing RTS games, as I can simply move the screen around with my scroll wheel, instead of moving my mouse to the edges of the screen. Also I don't have to move my fingers around all the time.
I use a logitech MX500.
