I've had quite a few. Lagavulin 16, Laphroaig 10 and 15, Glenfiddich 12 and 18 come readily to mind.
I am now experimenting with others.
I really liked the peaty flavor of the Lagavulin and Laphroaig, but sometimes it's a bit much and ya need to throw a change-up, ya know?
That's the beauty of scotch... so many flavors and variations of flavors.
