Which tea flavors go best with a mint syrup?

The tea flavors I have are blueberry, ginger (not very gingery though. Boo!), lemon green tea (no me gusta lim�n in my tea), earl grey, a teaspoon of loose rooibos, and Tazo's passion tea (fruity and very floral). Which do you think would go best for iced tea and mint?
