 Re: Asymmetrical curve vs. Symmetrical curve
Author: David Spiegelthal 2017

As the rubber of the mouthpiece (assuming it's hard rubber, as most are) ages, some of the constituent chemicals (plasticizers, sulfur, etc.) either offgas (evaporate) or undergo chemical changes such as from UV or oxygen exposure, etc. (Dr. Omar can explain far better and more correctly than I), and this, along with general material shrinkage over the long term, can result in dimensional changes to the facing -- including but not limited to the development of asymmetry in the curvature of the rails.

One great advantage of both crystal and stainless steel (or other metal) mouthpieces is that they are not subject to long-term dimensional changes (unless you count the 'creep' of glass over millenia -- yes, I'm aware that glass is actually a supercooled liquid and 'flows' over hundreds or thousands of years).
