I really need help with this. I play Alto sax, I have a Selmer S80 C* mouthpiece and I am looking in to trying out an Olegature. However, all of the websites say that the S80 mouthpiece needs a size 01 olegature. But, the only olegature's I see that they offer are 02 (which say that they go with a regular Selmer rubber). Can you use a 02 on an S80? I'm really stuck and any help would be greatly appreciated!!
