I think of BR as 1.5 streamlines...one from the waist down as you pull...and the main one after you finish the kick.
After the kick hold the streamline tight in your legs, right to your toes, as you transition to the pull to feel the waist down streamline.
It's more of a swim drill I've done to try to hold back the kick from "blocking me out" in the water. I don't know if it's working into my stroke how I envision...I guess times will tell.
