| Hi,
I actually have 2 mouthpieces that have basically the same cup and rim construction but have different backbores. The mouthpiece on my Taylor was copied from my GR but we purposely machined it with a tighter backbore. OK the mouthpiece is heavier than the GR but it has a noticeable effect on endurance and range..maybe at the expense of some tone but on the Taylor that's never in short supply.
The resonance/resistance thing is interesting. I play 2 trumpets that are at either ends of that scale..the Kanstul resonates like hell and the Taylor hardly does at all. Both are regarded as very 'free blowing' horns but IMHO the Taylor plays tighter (I believe because of the weight) even though it has the bigger bore. Interesting discussion though.
Just my observations.
Regards
