I have to admit I just skimmed through but.
The 6 paths have the same eyes as the person in control right?
Isn't it possible to change if you're using regular Sharingan, or EMS ?

Because at that moment Madara seemed to be using the same version + he doesn't have that many Rinnegan eyes to
my knowledge.
That being said, he had a chance to use both Rinnegan and remove his Sharingan did he not? Should we then not assume he found an advantage of having
both eyes opposed to just one?
Further more where's the proof that having just one Rinnegan weakens what you can do with it?
To go a step further let's look at having a Sharingan and a Byakugan.
Idk, it makes me think of having a gun and a knife for when you run out of bullets. Guns stronger for sure but that knife is going to give you more use in a tough spot.
Okay, maybe I'm reaching now lol.
