Long Island Iced Tea

I made my first attempt at long island iced tea this weekend. The recipe I got off the internet was really strong and it was too strong for me. My husband liked it though. I want to try to find a recipe that doesn't use tequila. I once asked a bartender why some long islands seem so good and others don't and he said it was because some use tequila and I probably like the kind without tequila. Or maybe I need to play with the amount of sweet & sour since that seemed to help. I tried adding more coke and that ruined it. I have since learned that the coke is just for color, not flavor. I will keep trying to perfect it!
