Steve, I have tried many cask strength, single cask whiskies. it is amazing how different they all are. They are different from aech other of course, and different from thier proprietary bottlings. I would highly recommend Black Bowmore 1964, Signatory Longmorn 1964, Lagavulin 111.4 Scotch Malt Whisky Society, Cadenhead's Edradour, SMWS Port Ellen, SMWS Caol Ila, Signatory 1980 Caol Ila, SMWS 19 yr. Royal Brackla, and on and on. Tasting is such fun.
