1) Is the ending formation in the last example (the one with Tidal Line) correct? (see http://www.ceder.net/def/endsbend.php) Centers should not move, unless they need to breathe - which, as I understand it, is done in order to get rid of the gap created by original Very Centers (along the long axis of the formation in this case). However, I would expect the original Center dancers to remain standing on the this axis. Do I understand the principle correctly?
2) What is your opinion on doing Ends Bend from a Line of Three? I think it can be done in accordance with the definition of yours as well as with the CALLERLAB one. However, the movement is not one's part of Bend the Line nor the original Ends finish facing if they were facing the same direction (they should end holding right hands)...
Ends Bend is legal from a line of 3. If both Ends were facing the same direction, they end facing each other. They do not end on the same spot with right-hands.
