Yes, there are a lot of staples that go into the rear bow, from the pads to the rear curtain to the top to the wire-on.
The top will lose it's wrinkles when it is stretched, it may take a little longer in the end before 18 years of wrinkles come out, but they will come out eventually.
The rear curtain without the wings is what I'd use. There should be pads to provide the same support in the same places, and the wings are just another layer to deal with.
No one lives forever, the trick is creating something that will.
