Re: a wee bit smokier than Highland Park 12?
Well, Talisker is smokey but not as intense on the smoke and/or peat as the Islay whiskies. It would seem that Talisker DE or 18 would fit the bill.
Other choices for the little less smokey would be Ardmore Traditional Cask, some of the peated Benriachs, or peated Bunnahabhain.
Otherwise, you are looking at scarcer bottlings like Port Ellen and Brora. Or moving up something much more smokey than HP - Ardbeg, Laphroaig, Lagavulin, Caol Ila, peated Bruichladdich.
