Thanks for the replies so far guys. I presently do have 5 bottles open, going back and forth, but not mixing them in one evening (one per night). Presently opened are the Ardbeg and Laphroaig 10 year versions, the Springbank 10, Aberlour 12 and Glenmorangie Original.
Finding that I really like the Aberlour the more I drink it. Sweet, flavorful, complex, even the finish is amazing. Better than any other Speyside I've had yet, and not at all boring. The Glenmorangie is similar (to me) in that it's fruity and sweet, wonderfully aromatic on the nose, but is softer than the Aberlour. Still an excellent dram for the dollar! I plan on putting a few bottles of this away as it's very affordable ($30 US).
The Springbank is turning out to be quite interesting. Nothing like the previous two of course, but bolder and aromatic in an herbal, almost medicinal smoky way rather than the soft fruits and spices of the Aberlour and Glenmorangie. It's a great whisky and I'm enjoying makng my way through the bottle, learning about my nose and palate as I go (this one is a real education compared to the softer fruitier malts).
The Laphroaig and Ardbeg speak for themselves! They are monsters, and I love them. A bottle of Lagavuin 16 is on my short list now, seems my Islay representation is missing the Big Dog (!). Also thinking about springing for a bottle of Aberlour A'bunadh, and Highland Park will be grabbed up on my next trip to the bottle store.
Onward and upward!
