I like the idea of the sweet/sour mix, too. Mostly, I use about half/half simple syrup and fresh lemon juice. I find that simple syrup keeps very well in the refrigerator.

Mike, how "fine" is your ice? cubes or crushed or what? I have a (GE?) fridge with an icemaker that produces those little truncated half moon deals. I just use those because I think the crushed is WAY too fine.
