I have a bottle of The Macallan Cask Strength that I'm still nursing, slowly.
My love is their 25 y/o... just can't drop that kind of money anymore. I remember when it was $200 a bottle.
Your suggestions, especially Balvenie's Doublewood are great! I do like Highland Park very much.
I have a soft spot for Blanton's Single Barrel Bourbon too...
