I recently had The Glenrothes Vintage 1985 at the Single Malt & Scotch Whisky Extravaganza and it was easily one of my favorites of the evening.
My notes...."Delicious! Very smooth, toffee notes, sweet, fruity, beautiful aroma and really creamy. Easily a favorite." So while I think you certainly have a great list of scotches, if you ask me...this would be my pick! Let us know what you decide. Enjoy!
