Natural Transition- Best Way?

I am transitioning to natural hair and I need to know if this look will work.  I want to leave very little of my hair out and I went to Sunnys Hair and Wigs in Atlanta and the girl who worked in there had this amazing kinky/curly hair.  It looks like 4a hair type.  I thought it was hers and she said it was called the Brazillion wave.  They sell it on their site its sunnyshair.com  but I want to know if any of you have tried this hair and how it worked out for you.  I figure I can transition this way because I could not tell at all that she had a weave and it was so cute.  But I couldnt trust the pros and cons she stated cuz at the end of the day she was still working in there so I need to know if any of you have tried this.  the pic is below.  The gyrs in the shop was curlier though- she said products and washing it curl it up more- or- you can straighten it.
