Ballerina set and Ballerouta set
Ballerina is a classic machine. With the Rewind, Reverse and Rewind Reverse, there is a Ballerina Quadruplet. I prefer to reserve "Ballerina" for the machine passing through Reverse Inside Star, and refer to the similar machine that passes through Reverse Outside Star as "Ballerouta".
With Mono Throne and Reverse Inside Star:

Rewind Ballerina.
With Mono Reverse Throne and Inside Star:

Rewind Reverse Ballerina.
The Ballerina Quadruplet:
