Okay. I can go with that. The vodkas have their same followers. Some are good on the rocks while others are horrible without a mixer. It depends on the filtration of it and whether its grain vodka or cheap home brewed potato vodka.
The low end stuff will really give you a headache if you consume too much. I've taken to the Swedish brand, Svedka over the last 6-7 years. It still comes in a glass bottle, which to me makes a big difference in taste. Smirnoff comes in plastic and it's become a rotgut flavor. Kettle One is good, a bit pricy, Stoly is way over rated as is one other that's in the same price range, I forget the name now.
Gray Goose has to be the best to me. It's smooth and doesn't take your tongue off. But it sucks to mix with. It's good straight up or on the rocks. I use grapefruit juice, Ruby Red, right off the tree in the back yard. Anyone that uses anything that contains processed sugar such as any soda/pop/whatever you call it is begging for a nasty hangover.
