Dont listen to them, New Breed is advanced yes, but it is progressive, is does break you in somewhat, this is the great thing about it, yes it will drive you crazy to begin with, but it gets easier every pattern you work through. Personally I did not find that difficult, there were occasions where I felt like throwing it away yes, but mostly just went through the motions with it.
As for practicing work through it like he says, practice nice and slow at first play each bar until you feel really comfortable with it, sing the bass, sing the hat, sing the parts like he says, He does mention playing through each bar four times, You will probably need to take more time to do that. If you find the voice excersises to hard leave them out at fisrt, and add them in later. It will take time, but is worth it. I spend about 30 mins a night working out of this book, and do about 2 pages a night,
Once you have been through the book once you can take it a step further, once you understand this system of learning co-ordiantion, and it is great system of learning anything, you can apply more complicated patterns, go through it with Shuffles and what not, different ghosting patterns etc etc. but for now just do what the man says.
As for stick control, i must confess, I dont use it a lot in my drumset practice.....a sin I know, but im sure you can find lots of interesting things to do with that book in the thread for things to do with stick control.
peace.
