HA! I remember thinking that way.
This is the method I would use in your shoes...
Make a 10ml bottle of each of those 3 recipes.
Take out another bottle and add 1ml from those 3 into the new bottle, shake, taste. Trust me, you'll be amazed, it's like a magic trick. Now take that 3ml bottle and throw it into a cup of hot tap water and take it out every so often and shake it until everything is room temp. and taste it again. Wow, the things you are bound to discover!
Now, after you find out that an even 1/3-1/3-1/3 blend does not taste like you expected, start with the flavor that seemed to be muted before at put in 1.5ml of that and adjust the middle flavor and the one that got boosted beyond expectations to make up the rest of the next 3ml. Taste, quick steep, taste and start again if needed. (There might be a time when an even ratio blend actually worked right, but I've never had it.)
When you find out the blend of these 3 that work, then deconstruct the recipe and record it. Put a star next to it. When mixing it from scratch for the first time make sure the "Base" flavor is put in the bottle first and then the other flavors, then add no-nic base and then nic. If it works this way, underline that star and brag!
