The wider Barrel 30 concentrates pressure on the tongue and further limits the nutcracker action. Bomber recommends the wider barrel to bring the head down without extending the nose.
The Barrel 30 creates pressure on the tongue, the Barrel 30 is slightly longer than the Barrel 20, this results in softer tongue pressure as the center component concentrates pressure over a larger surface area. The center component is a smooth, rotating barrel that creates a constant, even pressure on the tongue. Pressure descends onto the bars and due to the mouthpiece being a semi-broken mouthpiece, it will hinder creating a squeeze on the bars – the barrel hinders the mouthpiece to fold backwards therefore creating little, to no squeeze on the bars. The Barrel also allows for independent lateral aids. The Sweet Iron material was chosen as a metal option as it oxidizes. Oxidization encourages salivation and acceptance of the mouthpiece. The semi-broken, Barrel 30, has limited movement.
