les pooches....which one?

[Melissa and Willa Couch]

I have been researching les pooches brushes based on many recommendations on Doodle Kisses.  When I googled to find the brush I was thinking there was only one.  There are so many!  Which one do I buy????  I am expecting my puppy some time this year.  I got an email from the breeder that the mama has been inseminated and will be getting a  sonogram in a couple of weeks to confirm the pregnancy.  My puppy will be expected to have a fleece coat.  The mama is curly and the daddy is wavy.  Which type of les pooches brush do I need?  

Thanks to all and any advice will be appreciated.  I really want to keep a long coat.  I need to start out right!
