My rule of thumb for bourbon mixed drinks is simple: Any brand with ginger ale. I like the 100 proof on up bourbons. I have used everthing from Colonel Lee 100 to George T Stagg. I used to use 7-up or sprite but that is for flavored vodka in my opinion. Ginger ale is also great with other whiskeys/whiskys as well. I love Irish whiskey and ginger ale, but absolutely mixed with 7-up or sprite.
