I don't drink vodka much now as I prefer cointreau, but if there's none of that then I'm a fan of Karloff or Absolut vodka.
A few years back I found a lone bottle of cherry vodka lost in a sea of name-brand vodkas, and I bought it without hesitation because I love trying out new spirits. It was so good I downed it all that night, but I've never seen it again since. It's not like flavored vodka is hard to find here or anything, but usually "flavored vodka" is more like regular-vodka-but-you-can-almost-taste-orange/lime/whatever. This stuff had the alcoholic cordial-ness of a liqueur, but was still 40% like regular vodka.
I may have to hunt down this Grey Goose stuff.
Jam it back in, in the dark.
