Target Water Profile

[mr_beer]

I need some basic advice regarding the water profile selection process.

Start with a grain bill for an Imperial Stout -- BJCP 2015 20C style
Amount of water determined by BS3
Now for additions for ?better? mashing.  I am supposed to select a target water profile. 

And that is my question ? what is the appropriate target water profile for an Imperial Stout?

I would go with Black Full.
