I realize no one is ever going to try one of my suggestions, but I can't help myself here. If you must make it vodka, because it's generally flavorless, and it's not saving you any calories (it's all about the calories in spirits when it comes to calories), maybe try the below. I only know a couple with vodka, and if you try this easier one, you will probably give up the screwdriver completely.
French Martini, 1:1 juice:hooch. 2 oz pineapple juice, 1.5 oz vodka, 0.5 oz Chambord. Shaken is definitely preferred for its effervescence. The pineapple and Chambord add up to about 50 cal.
