The reprofiling, seems to me, is a result of engineering capabilities that simply didn't exist back in the day. Now they have the ability to quickly enter in parameters in an engineering modeling program and design the ride to where it offers a great ride but at the same time is engineered to maximize the durability of the ride. Back when it was first built, some of the sections of The Beast were literally "trial and error." As far as the trims, I would say at a minimum, they can maximize the trim's desired effect without having them be too intrusive.
