Start with 2 girls on the ground on their knees and hands, then place another girl in the middle of them bent over.  On the outside of each girl on the ground have a girl hitch to the inside.  Place the main fliers behind a girl on the ground.  Have them place their outside foot on the bases' lower back.  With the help of a spot, have the flier step and lock with her foot on the back of the base and hitch to the girl in the middle.  Have the fliers hit Hi-v's for the finish.

NOTE: you can place 2 girls on the outside on their knees for an added effect (as shown in this picture)
