Late to the party, as usual, but since Islays are forever I thought I'd lay my two pence in.
Uh, you're all dead on, basically. Laphroaig is my go-to scotch, period, as the price point is beyond beautiful for the ten year--you can get Bowmore for five or ten bucks less, but in my opinion it's fairly bland, at least for an Islay. Laphroaig's Triple Wood, Quarter Cask, and Full Cask are all amazing in their own ways, but as the price point increases my eye begins to stray to Caol Ila, Lagavulin, and cousins Talisker and (distant cousin!) Oban. I've been lucky enough to try the 18 and 25 year Laphroaigs, and while they are some of the best spirits I've ever tasted, I can't say I'd ever spring for the 25, even if I might one day splurge on a bottle of the 18--the difference in taste between the two is there, but far too subtle to justify the price of the 25 YO.
In re: Caol Ila, if you can find the Distiller's Edition, that is
well worth picking up. It's only a year older than their regular stock, as I recall, but transcendentally tastier. I've seen but have yet to splurge on Distiller's Editions of Oban and, I think, Talisker...
Bruchladdich's only recently become available at my local shops, and I've sampled three of their bottles to date--in order of cost, these are the Laddie Ten, the Organic, and the Resurrection Dram. They're all delicious, but at $55 the Organic was far and away my favorite. Pricier than the Laddie, which was forty and change, cheaper than the Resurrection, which was maybe $80, but leagues tastier and smoother than either. If you're interested in Bruchladdich, I'd highly rec springing for the Organic rather than the Laddie Ten...
And looking at this, I really need to give Ardbeg another chance--I tried a bottle years ago, and was underwhelmed to the point that I haven't tried a sip in years. Will have to go back to the well one of these days...
Amazing how thirsty I'm feeling all of a sudden...Oh, and
here's a link to the whisky section of the website of author and whisky-sipper Mark Newton who's my man in Havana, if Havana was the Scepter'd Isle.
