My personal soprano piece is a Selmer S80 that I have opened up to a comfortable "jazz" opening. I love Selmer rubber, and these have a great tone. Opening them up will accentuate that little classic Selmer "bump" baffle right behind the tip rail, and it projects like crazy while keeping a fine core. I wouldn't play a Super Session without enlarging the chamber, too resistant for me, but I've done several that have turned out killer players. Did I mention I love Selmer rubber? S80s will make very cool jazz pieces.

Erik plays on a .065" S80 (which would be like an I), I play on a .070" (about a J). The problem is that Selmer curves can tend to be all over the place, nonetheless like Mojo said each can vary in tip opening, so usually the length and rate of the curve needs to be addressed. Plus in taking a slightly closer one and opening it up, you can get more baffle into it. We charge $65 for hard rubber pieces, plus shipping of course. And I'm sure they can be opened up farther if you desire.
