If you're in the mood for that huge seaweedy hit, Laphroaig, particularly the 10 yo cask strength, beats any other Islay. But I only really get in the mood for that in the depths of winter. In more normal conditions, I go for the Lagavulin 16 or, on balance, the Distillers Edition, because they have lots of everything, but well balanced. I haven't been a regular enough Laga drinker over the years to say if they've "dumbed it down", but it does seem less extreme than I remember the old 12 yo being in particular. I have to say, I have recently got into the entry-level Ardbeg TEN, and am really growing to like it - it might overtake the Laga 12 in my affections. I actually like that lanolin/wool oil edge (I feel that Port Ellen and Caol Ila have it a bit as well). There isn't an Islay whisky I don't like. BUT ("come outside and say that" statement): none of them holds a candle to Springbank or Longrow at their best.
