I'm a big fan of squash/cordials/ribena/whatever (I drink it quite diluted) and I really love lime and soda. I find regular fruit juice too sickly sweet, I really need to dilute it with a lot of water when I drink it.
I'm afraid I really like it room temperature as well. I really really really don't like cold drinks, unless it's really warm, which it never is, in the north of Scotland.
