Yep you're right.I think saxes peaked a long time ago in design and construction, [and popularity]. I play 95 year old and 15 year old saxes interchangeably, so I think the "ergo" thing is exaggerated. I can't really think of a single performance-based innovation [not cost savings] to have happened in sax design in the last 60 years? Maybe longer.
As soon as they started tilting that pinky table and jamming it as close as humanly possible to the G touch, it's been downhill from there.
