I use Luzianne, also. I use 4 big tea bags per gallon, plus one small bag each of English Breakfast and Earl Grey for the citrus flavor (Twining's brand), and 2 small bags of green tea (it's healthy so I use it. . .but I don't like the taste. Any brand). I add just a bit more than half a cup of sugar for the gallon, because I don't like it unsweetened but I also don't like it too sweet. I don't like milk in iced tea, although it's a must for hot tea.
Sometimes I'll throw in a bag of peach-flavored tea or Tazo Passion instead of Earl Grey.
