The jury is still out for rubies. You could double your shares, but they are heavily on diminishing returns. You do get Prestige for lvl in decoration, but they do not double the effect with double cost (that is diminishing return, btw).
The xX Multiplier are useless as they are now, bc they are additive. You can wait them out on the wheel.
If the winnings on the wheel keep piling up, maybe the wheel is best. I got one "multiplier" and I could swear, the value of that price went up afterwards.
