I think you should be able to do a very good job with the Coat King and thinning scissors. Tilly had a very flat, silky coat before she was spayed ( I have heard it referred to as a "non-trim" coat) and was previously hand-stripped. Even after spaying I am managing to keep her looking respectable with the scissors and CK, so I would imagine your little girl will look gorgeous without having to clip.
Good luck - the advice in the pinned threads of this board is great!
