Dancing with Healing Vision Angelic Mix without turning into a pretzel

Stepchart referenced here.

In DDR 5th Mix there is a song called Healing Vision (Angelic Mix). On Heavy (Hard) it is a 9-step song. I have previously passed this song by "ghetto stepping" it. This means I've used the same foot twice in a row, hitting two consecutive arrows, for many of the patterns. However, I'm older and fatter now. I'd like to find a smarter way to solve this song.

Referring to the stepchart and considering jumps (two simultaneous arrows) to be single steps I see the following pattern:

Step 1: Jump (no problem) Step 2-8: Easy pattern Step 9-15: Another easy pattern Step 16-18: Seemingly easy pattern, twisting the torso to avoid ghetto stepping. Step 19: Oh no! Either I must ghetto step here or turn myself into a pretzel!

If step 16 is started with the left foot (my inclination), step 18 is also done with the left foot, but that leaves me in an ugly spot trying to reach step 19 with my right, turning myself entirely away from the screen to do so.

If step 16 is started with the right foot (an unusual choice), step 18 is also done with the right foot, and that makes step 19 an easy left foot choice. That also makes step 20 an easy right foot choice, but then I'm left in a nearly identical pretzel vs. ghetto step choice for step 21!

How can I solve my dilemma? Hopefully someone else on these boards is/was an avid DDR player in years past and can expound some arcane secrets to the masses here on the internets.
