While I'm more of a Cognac guy myself (Kelt XO, mmmmmm), I've recently been getting more into Scotch. For an every day drinking one, or an easy order at a bar I usually go with a 12 year Macallan. I prefer the 18yr and higher ones (which I'll drink at home). For blends, I don't mind JW green and up - quite like Blue. I went to a JW Gold event at the Foundation Room in Chicago and they were serving it very cold with desserts. Odd, but I quite liked it. I've never done it on my own though.
Great thread though, there are a few new brands i'd like to try
