I read your post in the Bourbon, Straight forum and noted your points regarding Single Malt Scotch. When I first got into Whisk(e)y, my preferred beverage was SMS, in particular the Islay Singles. I know that many say that it takes some getting used to the flavors/aromas of those whiskies, but I gravitated to them right away. In particular, I love the Laphraoig bottlings, especially the cask strength version. I also think very highly of the 16 YO Lagavulin which I know is now in short supply. Bowmore also makes a variety of good Singles. I've come to really enjoy the Bruichladdich products. I had the good fortune of tasting the 1970 version at WhiskyFest NY in 1992 and it was superb! Unfortunately, it is in such limited supply that I believe its about $300 per bottle, which is way too rich for my blood. Speaking of that 'Fest, I also had the 30 YO Laphraoig...very, very good, but again too expensive.
Regarding other Singles, I think that Springbank is excellent, I enjoy Macallan, and I think Talisker is another very good drink. I like the peppery flavors that are evident in the Talisker.
I've grown away from Singles though, and have been enjoying my explorations of bourbons much more of late.
