Start with 2 shoulder stands (or elevators) on the outsides and a shoulder stand ( or elevator) in the middle. 

For the inverted splits, place 2 bases next to the middle shoulder sit facing forward, 2 bases with their backs next to the outside shoulder sits, and 2 fliers between each facing out.  Have the flier grab the shoulder of the outside base and have the outside base grab the shoulder of the flier.  Both individuals should place their hands with their thumbs down.  Have the other bases stand to the side of the flier (which is at the back), and place her hands on the fliers' front hips and thigh. 

On count the outer bases bend slightly down, the fliers will jump and push off of the outer bases, and the inner bases will assist and push the fliers up by stepping in and grabbing both sides of the fliers' hips as she goes inverted.  The fliers need to make sure that they split gradually as they go inverted (don't snap the splits).  Now have the fliers split/hitch to the shoulder sit fliers on either side for the finish.

NOTE: you may use another base to assist with the flier going inverted.

NOTE: This pyramid is inverted and is restricted by most if not all Jr high and High school teams.  All Star and College teams should be able to do this pyramid just read your rules and regulations to be sure.
