Hi:

Does anyone have a good facing curve, (Morgan guages) for a rubber 
Link soprano mouthpiece.  The one I now have is a 10, (way too big).

Thanks,

Bob

There are a couple of Excel files in the Files - Sop Sax section 
that you can use.  They say Selmer and Dukoff but you can use them.  
Just pick a tip opening and facing length that looks good to you.  
Plug in your Morgan feeler gage set and the facing length numbers 
should update automatically since they are calculated from a radial 
curve equation.
