Some recent pickups that I've enjoyed.
Bladnock 10 (yes, it's a Lowlands, but every person who's tried has really liked it)
Glen Scotia 15
Benromach 10 Imperial Proof (57%)
Great King Street Artist Blend (from Compass Box. Mostly for my wife, but nice when you want a light dram)
Have tried my hand at blending and had some fun making a couple of malt blends that turned out quite well with a bit of tweaking. Nice when you can turn blah single malts into something you're excited to drink.
I also blended two American whiskeys I have not been crazy about, Weller Special Reserve (2 parts) and Old Forester Rye (1 part), and it turned out great. If you have both bottles, I suggest you try it and see what you think.
