For James's tea, I use 4 family size LUZIANNE tea bags to a gallon. I add about 1/3 of the water to it, almost boiling, to steep the tea bags, then I add cold water and refrigerate. James likes his tea with no sweetener.
For my tea (or as James calls it, pancake syrup) I do it the same way, but when I add the almost boiling water, I add one of three things. For my favorite tea, I add close to 2 cups of sugar for a gallon pitcher. For my second favorite, I use about 1/2 cup sugar and the rest store brand Splenda. For my least favorite, but still good (when I'm trying to be good, lol), I use store brand Splenda and no sugar.
I discovered Luzianne tea 15-20 years ago and have preferred it over any other since. I can always tell when a restaurant is using Luzianne.
So smooth, and perfect for iced tea.
P.S. Because of something stupid
my cousin and I did when I was 10 and he was 5, I cannot stand lemon in my tea, so I just drink my tea plain, with sugar/sweetener.
