@Newell-Post said in Mouthpiece recommendations for young beginners:
10.5C Readily available, cheap, used. Worth a try. I never liked the 7C, even when I was a beginner, due to the shape of the rim. (Very sharp inner lip and heavily rounded outer lip.) I don't know who ever came up with that concept or why. But, for me, it was terrible for endurance. The 10.5C is slightly smaller, but with a fairly flat rim that is much more comfortable. IMO.
Well, the 7C worked for me. The smaller sizes never fitted, and now I am on a 1C Megatone that I had specifically altered to emulate the sharp rim of the 7C...
