Shoulder (elbow restricted, wrist locked), for when you want:
> long lines> to cover large areas> smoother, long curves> to be more spontaneousWrist (elbow restricted, shoulder forgotten), for when you want:
> finer detail and motion> smaller marksElbow: somewhere in between.
All that said, "less flowy" seems weird to me. I think what you're experiencing is a lack of experience drawing from the shoulder, and are therefore feeling constrained. In fact, when drawing from the shoulder, lines are much more flowy, and you can be pretty spontaneous with your motions when drawing from the shoulder. For example, if I'm drawing long strands of hair, I don't want to be drawing from the wrist because I'm thinking too much about where I'm going next.
So keep practicing drawing from the shoulder or the elbow, but don't fall into the trap of thinking that you should ALWAYS do that. There's a time and place for every tool available to you. You just need to learn where to use them.
