Chris, just one thing to think about: other than the ad on the internet and a couple of testemonials, who says that the physics are in fact better? Do we have any other "dicliplines" (automobile manufacturingor similar)where an asymmetric valve (the lip does not vibrate like a clarinet reed in free space, it works like a valve completely opening and closing) is used to advantage? Just because my two lips are of different "thickness" when in a relaxed state, does not mean that a mouthpiece has to be "asymmetrical". I'll take another look at the geometry and math - last time, I was underwhelmed. No cut on players that have been able to make this work. I suspect the improvement had NOTHING to do with the rim shape, rather the cup volume, throat and backbore: all things that I can optimise in conventional mouthpieces too. I am not sure if we are chasing a paper tiger here.
