For a traditional single malt scotch that tastes like a refined blended (Famous Grouse, Dewars, Johnnie Walker Black, etc...), try a Speyside or Highland whisky. This will be similar in taste to most of the blends I have tasted.
Speysides and Highlands include quite a few: Glenrothes, Dalwhinnie, Balvenie, Glenfiddich, Glenlivet, Macallan, etc...
If you want to try something that you just can't get in a blended, try a wood-finished whisky. These would include Balvenie 12yr Double Wood, Aberlour 12yr Double Casked, or Macallan 12yr for a lighter finish.
If you'd like to try a peatier/smokier malt, try Bowmore, Laphroig, Lagavulin, or for a lighter taste than these heavy hitters, the Highland Park.
If I lost all my whiskies, the first one I'd replace is my Macallan Cask Strength, then the Aberlour 12yr.
