Start with 2 shoulders stands in the middle and place 2 thigh stand stags on the outside of them. Make sure the stags are stagging out.  

on count have the base under the shoulder stands place their outside hand under the inside foot of the fliers. Now have the fliers shift their weight to the inside and hitch their outside leg to the outside flier in the stag. Hit Hi-V's for the finish

NOTE: the middle shoulder stands can connect together by wrapping their inside arms around one another for an added effect.
