If you already have Ghost rollers, get these and make them full time camber cups THEN get the Bremmy rollers for the best experience of all worlds. These are fine and work with the Duffalo bar well. You will like having them, but don't view these as something you will realistically swap out between uses.

These are a one trick pony and too expensive overall, but extremely helpful for the proper use of a Duffalo bar.
