Bicubic smoother is best for upsizing in the amounts you indicate. And you really don't gain anything by doing it in steps. In fact, you introduce more opportunity for errors. Genuine Fractals offers advantages in huge upsizes -- alont the order of 300% or more because it doesn't work at a pixel level. It's useful when generating an image for a billboard or something like that.
