Ever since I first picked up and had started using a game pad controller for console & computer gaming (in the 80's), movement was always controlled with my left hand & left stick or thumb pad on the controllers. Right hand always controlled most the other functions, so I can't escape what feels natural to me holding what more or less ammounts to a big game pad.
I understand some people worrying about not having self-centering on the throttle stick, but I actually like it without that feature! Well, I do so far, though I'm sure a time will come where that will bite me in the a** for having it that way ... LOL
Other than the possible issue with the above, I'm really not sure why more people don't seem to like the way I have mine set up, with throttle & direction on left stick & all other tank functions on right stick. Seems like most, or at least the vast majority like the opposite of this way.
