What's the best looking Syandana For Excalibur?

New to warframe and looking to get nice looking Cosmetics for Excalibur. Right now I'm rocking the Izvara Syandana but that awkward outcrop that attaches it to the frame is now starting to get to me. Is there any kind of Syandana that could completely hide the darker looking sections on the back of the Warframe? I'm open to any suggestions, even if they're only obtainable with prime access.

Also, any suggestions on arm/leg/chest cosmetics that would look good on Excalibur would be good.

Any ideas?
