Difference between Bach 5, 5G and 5GS?

For example, playing characteristics and sound.
If you scroll down on this website http://www.mouthpieceexpress.com/media/ ... hmouth.pdf that has all of the Bach mouthpieces listed you can find the differences.
From what I found on the page
Bach 5 - Medium depth of cup
Bach 5GS - Same as Bach 5 w/ a larger “G” throat and a #420 backbore
Bach 5G - Deep depth of cup w/ a .276” throat and a #429 backbore
From my understand going from the 5 to the 5GS to the 5G the throat, backbore, and depth of cup get slightly bigger.
