From what I have seen, the Virtual is a much stronger ball than the Sauce, especially on oil. The Sauces I have seen were more rolly, whereas the VG reacts strongly to friction for a sanded solid. Way more backend than your traditional heavy oil ball, it seems to save energy better than most do. Just my opinion.
