Apparently the Grey goose is the best vodka (according to the observer from last year). In my opinion the Grey goose is very nice and smoother than other ones. And believe me I have tried many - cultural thing - I am Polish
All vodkas got the same points values apart from a flavored ones because they might have more sugar.
My ww stuff also says Malibu 25ml is 0.5. Sounds like a bargain - less than gin!
just to let you know malibu is one of those wierd things like bread 1 shot is half a point, but a double is 1.5, cos of the way figs gets rounded up or down.
