Having worked in the whisky trade for a number of years, it was interesting to read through this.
My own preference are the Islay Malts which I think are all very good. They are not all heavily peated - try Bunnahabhain or Bruichladdich. Laphroaig 15 or the very affordable Quarter Cask are top notch. Lagavulin is excellent but over-priced as they can't keep up with demand. Bowmore 17 or Darkest, anything from Ardbeg and younger Caol Ilas all hit the spot.
Away from Islay, Highland Park, Clynelish, Macallan, Balvenie would be in my malt SPL.
However, my Christmas gift to you is this word - Mortlach. Without a shadow of a doubt, in my view, the most under-rated of all malts. If you know anyone who is a member of The Wine Society get them to order you a bottle of their 15 year old 40% (under £20) or the cask strength (under £30). Both are absolutely outstanding.
