I don't have Kid yet, but I do have Brule and Cork amongst the other shades you mentioned, and I love them. I use Brule all the time as a lid shade, and I love to use Cork/Soft Brown/Wedge/etc. interchangeably in the crease. It's definitely not a highlight shade (for my NC20ish self), but it's awesome for the lid and for blending out harsh edges. Cork is just a great mid-tone brown shade, and it works wonderfully in the crease with a variety of shades.
