Start with the flier facing the base.  Have the base bend down at his knees and place is arms in front. 

On count the flier will do a hand stand and initiate herself over so it simulates a front handspring.   The base will grab the flier's lower back with his hands open, and lift her up, and push forward with his left land on the flier's right lower back to make the front handspring flip and do a half turn.  The flier will need to give a shrug off of the ground, squeeze her abs, tuck her chin to her right shoulder, and hollow out.

After the base tosses, have him reach high for the fliers feet as to hit a toss cupie.  Squeeze for the finish.  The flier will stay tight, squeeze the middle of her feet together for the cupie, and hit a Hi-V for the finish.
