Thanks for the excellent description! Can't say my palate is sophisticated enough yet to pick out fruit aromas and the like, but totally relate to how you describe the experience.
This may be heresy, but I have been experimenting around with going back back and forth between the Lagavulin and the Laphroaig. One drink of one, then one drink of the other. Knocked back about 6 drinks in this manner the other night. Both have such huge lingering finishes that switching jars the senses a bit, but thats good because it makes me notice the difference, and within a few sips I'm completely acclimated to the different experience. So far I'm finding it impossible to say which one I like better! In short:
Laga: big smoke, lots of complex flavors, super smooth
Laph: HUGE smoke, intense but simpler flavor, definately commands notice
Can't wait to add the Ardbeg 10 to this mix and see where it falls.
