2) Pretty well any of the San Pellegrino range, but particularly partial to lemon or grapefruit. Izzy are ok, if a little sweet.
3) Disgusting stuff
4) Don't know what the difference between Lemon-Lime and Citrus is.
5) Never had it and it looks and smells disgusting
6) Haven't had Ginger Ale for years but Canada Dry was always the best.
7) Strange that this thread doesn't include Ginger Beer which has all sorts of amazing options.
