I would of kept the double at :40, it's a cool L to R tremolo thing there when you pan them. Most of my doubles I kept one take center, and the double high passed and sent to a micropitch shift to get some width. That sounded better to me than just panning the short widdlys L and R.
Somehow there is a lot of distortion in the mix. Kind of sounds like pushing into a clipper too hard or a limiter with short lookahead doing way to much gain reduction. Whatever it is I'd back out of it to get a cleaner overall mix.
