Deciding Majors .. Aerospace/Mech .. or Both as Dual Majors .. !! ..?

I would say one or the other; while a dual major would look impressive, I think that if you wanted to work in the Aerospace industry, you should just stay with AE. It certainly wouldn't hurt, however, to have both degrees, but if you plan on working towards a Master's degree, I would recommend you stick with just one minor.
