[Gerardo]

I use both hands equally when I steer. If you can get the job done, the fans have no idea which hands are working harder, so.........

But if you'd like to make things easier, why not evenly distribute your muscle effort between both your hands? Might offer more precise control.

Jim, keep this toward the bottom of your list of things to worry about.

Michael, has your thumb made you think about this in more detail?
