Except they really aren't. The company tells them to tell skaters they are the same, but the rocker is flatter than CA.Coronation ace are great for spins and jumps up to doubles but there are supply issues right now so I would recommend Jackson Ultima Legacy 7. I’ve just changed to these from CA and they are pretty much the same just a lot lighter and my spins are much faster. The man at the skate shop recommended them as they are almost identical to CA.
