To avoid carpal tunnel, keep your wrists high -- that's why so many devices to aid or avoid carpal tunnel involve supports for the wrist. The worst thing you can do is rest your wrists on the edge of the desk or keyboard tray.
When I was a kid, I took piano lessons. I hated them eventually dropped them. But my piano teacher spent five years teaching me to keep my wrists high over the keyboard, so that my fingers dangled down below them; makes it easier to hit all the notes. When I switched to a typewriter keyboard and later a computer keyboard, I kept that same high-wrist position. And in over 30 years of heavy keyboard use, I haven't had the faintest twitch of carpal tunnel.
