Cocktail recipes for someone who likes sour cocktails over sweet?

I like cocktails such as the Singapore Sling. Ingredients I like are:
gin, cherry brandy, soda water, cranberry juice, lemon/lime juice

Any favourite receipes you can share?

I like Amaretto sour:
*1 1/2 ounces Amaretto
*3/4 ounce Lemon Juice
*1 teaspoon Superfine Sugar
Shake with ice and strain into a glass. Garnish with a slice of orange and a cherry.
Instead of lemon juice you can use Sweet & Sour Mix.
Enjoy.
