Personally if I'm going to drink Vodka I'll take it straight , be it Stoli or Grey Goose.
My long lost brother. Flavored vodka is for pussies. That is, unless you're making wedding cakes for a group, those shots are good enough to allow a bottle of vanilla vodka in the house.
The only thing I'd have said differently is that if you're going to pay the money for a good vodka ... switch to bourbon instead. That's the only adult beverage worth > $10/shot IMO.
Stolichnaya is good enough to pass as top shelf in my books.
And another question, why the hell would someone ruin the divine taste of Jager with Mountain Dew???? Red bull perhaps, but the dew? ... rednecks
