Which group feature requires half of the team to rotate in the opposite direction?

The requirement for half of the team to rotate in the opposite direction is specifically a characteristic of Different Rotational Directions. In synchro skating, this feature helps to enhance the overall visual effect and complexity of the performance. When teams execute this feature, it showcases the ability of skaters to maintain synchronization while moving in contrasting directions, which adds dynamics to the routine.

Differentiating this from the other features: Change of Edge refers to the skaters altering the edge they are using (inside or outside), which does not inherently involve opposing rotations. Difficult Position focuses on the elements that demand challenging stances or formations from the skaters but likewise lacks the directional rotation aspect. Change of Hand typically relates to how team members relay or hold hands throughout maneuvers, and it does not specify the need for opposing directional movement. Thus, Different Rotational Directions is distinct in its requirement for half the team to rotate oppositely, thereby clearly establishing it as the correct choice.
