Crucifix
From Acrobalance
Crucifix is a simple balance, both a transition move and a trick in it's own right.
Mounting
The simplest method is from Justice, with the base reaching up and placing their hands in the flyer's armpits. The flyer, keeping their arms straight and out to the sides, presses down hard, allowing them to lift their feet from the base's legs and be held there.
Dismounting
From here the flyer can go back to Justice, or into a number of other moves, such as Sack of Potatoes or Swallow. Sack of Potatoes and cartwheeling out is a good way of getting down.
