What kind of entry variations can be selected for the synchronized spin element?

The selection of entry variations for the synchronized spin element can include moves such as the butterfly or stationary pair lift because these specific entries enhance the artistic and technical aspects of the spin. Including defined and recognized moves not only showcases the skaters' technical skills but also contributes to the difficulty level of the element, which is crucial for scoring in synchronized skating competitions.

This means that skaters must choose from specific options that are compatible with the synchronized spin, rather than from a broader range of entries that might not fit the required criteria for that element. Using these particular moves allows teams to create a more cohesive routine while adhering to the rules and expectations set by judging criteria.
