The fbc is a rabbit hole which is why some now say its a none teach.. Fairly difficult to move forward without some type of coil. We know that gaining ground by stretching the core forward yet back doesn't have a large dependency on coil.
Maybe fbc does matter for the folks that believe the stretch is between the rear leg/hip and hands.
