If you're bothered that some icons are not "properly" skinned, try
to
Clean Icons - Cold

or
to
Clean Icons - Thin

I prefer Clean Icons - Thin because Clean Icons - Cold desaturates the icon colors. It's a cool effect though!
Each one is about 70MB but since it just skins icons, it doesn't have any impact on resources.
