Landgraf babies v. Corde la bryere babies

My family has been thinking about breeding our mare again. She has only been bred once, to a C line holstiener. I have decided I am in love that line, but I was wondering what Landgraf babies, or common traits in his line of offspring were. I was wanting to know your guys opinions were on the different lines, and the kinds of babies those lines made. And if you guys have any information on Selle Francais lines please tell, I have heard a lot of great things about that breed. Thanks for looking.
