The current spiral sequence is being modified to add an outside forward spiral. The end of the sequence is altered slightly; the whole first section up to the triple three is unchanged.
A new serpentine step has been created that uses portions of the current quick edge step and adds counters, twizzles and loops that are not in the current move. The emphasis of this move is edge and turn quality as opposed to only quickness. This new move culminates the training of body control, use of edges and the turns learned in the prior moves tests, and demonstrates them this time at a senior test level of performance.
