Help me Decide Which Inuit to 100% on my Sky Pup

Just as it appears above!

I have a Sky Lady that I'm looking to raise the opacities of and beautify! I have two of the four marks decided, but the other two are double Inuit, Gray and Black.

I really like either or I think, but doing both would be a waste of GC (since one covers the other obviously), or would it have a good purpose for breeding and genetics possibly? Anywho!

Here's the Wardobe Link (with other markings at 100%, but Inuits at current opacity)

I personally think you should do both because 1, it dose change the look to a darker grey but not black  and 2 ( you can ask in chat) but I was told the pups mark opacity is directly effected by the parents marking  opacity
