Notes:
  • At A2, Switch To A Diamond should only be called from a Wave; and Switch To An Hourglass should only be called from Parallel Waves. At C1 and above, these calls may be called from any legal starting formation.
  • On any Switch call, Centers do a Run (flip away from the Center of the formation).
  • Switch To A formation:
    Centers Run as Ends do your part of a formation Circulate. Usually ends in the given formation.
  • Some glossaries define Switch To A Diamond as Centers Run + New Centers Hinge. We believe it is better to think instead about the Ends doing a Diamond Circulate. This simplifies learning future calls since you can apply the same rule (i.e., a formation Circulate) to three calls (Switch To A Diamond, Switch To An Hourglass, Switch To An Interlocked Diamond). Would you rather memorize three traffic patterns or one rule that you can use for all three calls?
