Taught my son to fish on a spinning reel. When it was time to step up to casting reels got him a left crank curado (age 10). He's good with it. I borrowed it once and could not believe how much better that is than the right hand crank. In the process of switching over though I have a dozen or so right hands.
I'll probably stick with the right hand cranks on the salt gear and go left on the fresh water stuff.
