Flavor of Whey to Mix With Surge

I am only going to be using one scoop of Surge post workout,but adding an additional scoop of whey to increase the protein.
I am trying to decide between the original and the chocolate. If i got chocolate, then I would obviously just add a scoop of choc flavored whey.

But my question is, if I go for the original, what would be the best flavor of whey to add to it? What does it taste like? Would vanillla or orange flavored whey go good with it? Also, is the BCAA content the same in all flavors? 13 grams per serving?

Surge is already made to give you the 2:1 carb to protein ratio…if you want a different ratio why not just use something else? If you want more of a 1:1 ratio why not just have 2 cups of milk and a 1/2 scoop of whey?
