I'm currently trying to work with New Breed and I find it extremaly challenging. I don't have a teacher at all so I have to work out everything myself. Basically, I just follow what the book says - first I play the system for as long as it takes to memorize it, than I go to the melody page and try to sing it, after singing it I play it with the required limb and finally while playing the system and melody I sing the quaternotes - I've found this to be the most challenging thing for me

. By the way I think that it is good to master each bar of the melody individually and than gradually connected them into segments before playing the whole thing.
Hope this helps.
