Using rings without the shift aids usually results in shifts that are both better and worse. Better in that no longer will the chain only climb up onto the larger ring at these shift points. Worse in that the rider often needs to learn how to help the shift with "soft pedaling" during the shift.
BTW one can file down the tops of pairs of teeth at a few locations along the ring to create a home made "W Cut" shift gate. I have done this many times on both self used bikes and for customers. Andy
