My favourite daughter got me a bottle of the Balvennie Caribbean cask for my birthday, very strong rum influence initially but that's died off a little as I've gone down the bottle, I'd recommend it as an alternative to sherry cask whiskies.
My top 2 of owned whiskies at present is
1 - Glendronach Allardye (18YO)
2 - Highland Park (15YO)
But the best I've had was a Bowmore 18YO Vintners trilogy matured in Manzanilla casks, absolutely brilliant but can't be found anymore sadly or I'd have broken my spending limit for a bottle
