Ah, Bunnahabhain, which is much easier to drink than it is to spell or say.
Dom, like all of these things, one person's favourite may be another's poison. For example, I've always thought Glenfiddich highly overrated. Favourites vary over time and circumstance and even with different expressions of the same malt. For a light dram I very much like Glen Scotia, if you like Laphroig you might like to try Caol ila. My particular favourites at the moment are certain Ardbegs, Balvenie Doublewood and a Macallan although I can't remember which one off the top of my head.
