Two 'opposing' options immediately spring to mind...
The first is Balvenie 15 Year Old Single Barrel (it ranges from just over 47%ABV to 50.4%ABV depending on the particular issue). Aged exclusively in ex-Bourbon wood, this beautiful, focused expression of the distillery style is laced with intense honeyed fruit and vanilla.
The second is Aberlour a'bunadh, drawn from 1st and 2nd-fill Oloroso wood and bottled at cask strength (just under 60%ABV). Those Jerez casks imbue the whisky with an astounding richness that simply glides over the palate - easily the equal of a fine Bourbon or Spanish Brandy.
