Single malt scotch is the only hard liquor I'll drink regularly.
Bowmore is too light for me
Laphroaig 10 is very peaty but very aromatic
There is a Laphroaig quarter cask that is available and is excellent also
Glen Morangie is excellent but I prefer the Sherry casked version best
Highland Park is great and the wife likes it as much as I do
Macallan is great also.
If you like cask strength scotch rather than "blended" single malts (as some of the single malts are) try joining the Scoth Single Malt Society.

They aren't cheap. Bottles start at $100. I had one that was 32 years old and 132 proof, casked in sherry oak which was outstanding. It set me back $210. They buy the full barrels from the distillery, bottle it and sell them to the members. Once they're all sold that all there is.
