We made the green cards in Viticulture - the ones with the grapes on them - more of a market. So there's always two visible that you could choose from, or you could draw the top card of the deck.

You lose out, I suppose, on hiding a strategy where the other players don't know what you're going for, but I think it more than makes up for it by reducing the luck element of what grapes you're able to grow. We found that being dependent on the shuffle for both the grapes and the orders could make for a very frustrating game if you consistently had unlucky draws.
