That's the most wanky lot of bs ever. You can't say you only like single malts, but not mention which regions. They vary so much region to region they're completely different drinks. Same goes for blends. Depends what the blend is going for. It could be a blend of a load of similar malts.
Frustrates me to no end, this idea that single malt automatically means better. It just means specific characteristics. If you find one you like, great, but if you don't it's hit and miss. You were being very specific in your post about everything else, so I refuse to believe you wouldn't have mentioned what you look for in a single malt, your favourite single malt or at the very least favourite region if what you said wasn't just wank.
I love a good Scotch, but I don't limit it to loving a malt or a blend. Johnny Walker Blue (a blend) is ridiculously expensive (and over priced) but is one if the nicest, most balanced whiskies I've tasted. I know it's also not fashionable for those talking up single malts because it's a big global brand, but it's damn smooth and damn nice.
Got that out of my system, now, to the rest of the response
