Liquor and soda recommendations

Just wondering what your guys go-to (simple) mix is. I have been experimenting with a lot of different flavors of both sodas and alcohol (different types also).

Last night I found my favorite so far. No this isnt a fancy drink by any means, but Veil whipped cream vodka and Fanta is the BOMB. I also tried with vanilla vodka and that was rather disappointing.

Whats your favorite liquor and soda mix?
