The Ace remains in the range. The Sprint is a pure flat water racer. The Ace is intended for flat water to choppy water. The All Star kicks in from choppy water to open ocean conditions and is also the better choice for surf race (BOP) courses.
The Ace does a lot of things very well but the one thing it's not so good at is riding a controlled overhead wave in to shore.

The All Star should be a big improvement if that is what you intend to do with it.
