A fixed mouthpiece and a soft breathing tube causes the tube to sink into the snot when correcting the position of the breathing tube, and then the breathing resistance increases imperceptibly. Good idea, but the joint of the mouthpiece should be rotating, not fixed. The plus is that there are no extra valves.
