I really haven't had too much vodka straight. I tend to use vodka in a cocktail or highball. I do enjoy Absolute. Or Smirnoff Rasberry. The best way to drink vodka IMHO, is in a Super Nova Vodka Soda. Club soda, Lime Slush, any kind of vodka, flavored or plain and some frozen Berries.
If I want to drink something straight, it would be a scotch, cognac or liqueur.
