I'm having lots of fun with Dawn.  One of the key differences in her is 2 neck bones, 2 chest bones and 2 abdominal bones.  It makes for some fantastic ability to pose her well.

 

Keep in mind if you have the PP 2014 that most of V4's wardrobe is easily converted to Dawn.  I've converted several outfits with ease.  Shoes are a bit of a challenge.
