When it comes to selecting between brass and steel pipe screens, it ultimately boils down to personal preference. Both types of screens are effective at preventing debris from being inhaled while smoking. Brass screens are softer than steel screens, which some smokers prefer because it gives a smoother and less harsh taste when inhaling. Brass screens are also adaptable to fit various cone piece shapes, making them a versatile option. Steel screens, on the other hand, are generally more robust than brass screens and can last longer with repeated use. They are also less likely to deform or become misshapen over time. Ultimately, the choice between brass or steel screens will depend on the smoker's preferences and needs.
