Out Roll Circulate can be done from any Line, anywhere, if
the caller designates who is preferred as the 'Out-Roller'. For
example, from Out-Facing Lines, the caller could say
Prefer the
End Boy for an Out Roll Circulate. In this case, the End Boy
does a Circulate (or a Trade to the far End), as the Others
Flip (180°) one position toward the 'preferred' End's original position.
