I noticed they are advertising on this site. In light of that (or despite of that), does anyone know about these mouthpieces? Any users/lovers/haters (based on actual experience, of course)? They look interesting to me...and I have a fondness and appreciation for stainless, having fabricated with it before (or at least tried to...it's a biatch to work with!) ...Seems like they would have a nice resonance to them. They also use Titanium, which also is interesting.
