I can think of no advantage to this beyond marketing. What is interesting, is that having a top edge comprised of a flange destroys any claim of superiority intrinsic to the straight edge that has been a hallmark of these drums since the beginning. To me, that means this marketing effort is based upon either collective amnesia or hyperbole.
