I personally like to have whisky (any alcohol, really) over a very small amount of ice. Purists will say that's a terrible idea and you can ruin a good whisky that way -- the trick is to just drink it quickly before the ice melts lol (yes I've tried several different types of whisky stones before, none of them do it for me).

Personal favorite scotch for the last couple of years has been Macallan 12. Wifey digs Balvenie. I find Glenfiddich to also be a really good option that's not quite so pricey -- great for a casual sip after work type of situation.
