Seriously. Something would pop in your brain from attempting to catalogue and data mine everything that was occurring that was being taken in by the use of those two eyes. I'd see it something similiar to the Zero System of Gundam Wing.

I'd definitely prefer the White Eyes, over the Copy Wheel. They're intimidating, and occasionally scary, as hell. Remember when Neji was staring down Hinata? Sheesh. Although, who would want to walk around all day with veins bulging from the surface of your face?

So, for regular day events, when not aiming to scare small children shitless with the Byakugan, I'd like Tsunade's eyes. Everytime they show her eyes they remind me of a lion's eyes, with the color and everything. Granted lions have poor vision, it's a captivating color and look.
