Order the Xtreme FO as the staying power is much better. Although the price is higher, you are not paying for as much water or dilution ingredient. And you are not paying the shipping on that water either. I love their Bellini and their Rice Flower and Shea
If you are satisfied with the Ultra, that's what to order. As I remember the RF&S behaved OK. You can always add it to the oils and blend well before adding the lye solution.
