big bore/big chamber, small bore/small chamber?

I've noticed while trying out mouthpieces, that there is a big difference between my old Selmer Signet and my new Chicago Jazz Series in responsiveness with the same mouthpiece.

My own BergLarsen Steel 115/2/SMS responds great on the Selmer, but is more difficult to play, especially in the low register, on my CJS. The sound is great, but it requires a lot more control.

On the other hand, trying a Lebayle jazz (great mouthpiece by the way!) I noticed it played beautifully on my CJS, but had a boring sound on my Selmer. I didn't buy it (yet), I want to try out some other ones before getting me a new mouthpiece. But it's defenitely a candidate, more than the dukoff I tried (honkin' only), or the Meyer (far too classical for me)

I believed I read something here about an influence of the bore on the size of the chamber optimal for that saxophone. Is there any mouthpiece specialist willing to shine a light on this? It would help me in my search for a new mpc, as it can narrow the search.

Thank you in advance.

Several of the books on woodwind acoustics state that the volume inside the mouthpiece (in the area past the end of the neck) should closely match the volume of the "missing cone" if the sax neck were continued to an imaginary apex in order to work properly. In his book "The Saxophone is my Voice" Ernest Ferron describes this in detail and gives a method to measure and compute the area of the "missing cone".

It would follow that a larger bore saxophone would have a larger missing cone area that would be satisfied by a mouthpiece with a larger chamber. It should be noted that the "effective" mouthpiece volume is a bit difficult to measure because it involves the area where the reed vibrates as well as the space actually inside the mouthpiece itself.
