Poll - Pixie or Sixie? (Patreon)

I'm curious which version of Pixie we should use going forward in The Bimbo Next Door Three. I'm not talking body shape. I'm just wondering which version of her skin.

Should she revert back to the semi-mechanical/android version of Pixie's skin from Chapters 6 to 12?

Or should we keep the human skin version of Sixie from Chapter 13 on?
