Re: Lefties...
Thomas,
"Never heard so much boll**s in my life."
I never said it wasn't boll**s - I just said it was what my instructor told me! Regardless, it worked for me anyway. I don't think there is any doubt that we all have a dominant "hand", it's just how well you adapt to using the other one for what are initially non-intuitive tasks.
As for cross-controlling, some well -documented incidents (and at least one crash) on Army Gazelles, where the LHS Instructor grabbed the RHS student's collective to fix the problem, with predicatable results. It was introduced as a teaching point on the Ac Commanders syllabus to show how exciting your day gets if you try to control the RHS collective from the LHS.
