Whiskey and coke. It's a shame to blow a single malt on such a tripe drink but something like what you've posted I wouldn't second guess. You can get fancy cokes for fairly cheap, and have it as a treat drink very infrequently.
That's what I use it for. I like whiskey but as only the missus buys me nice stuff, I usually end up with several cheap bottles at Christmas from other people. I save them for when people are over and want whiskey and coke as to use a single malt for that would be sacrilege!
