What I am saying is if I can get a reasonably good sound with a cheap plastic mouthpiece I should be able to get a better sound with a quality one and I would like to have it as easy to play for me as the cheapie. Now , back to the original question. Does anyone have any suggestions what that brand and model would be? I don't mind spending a few bucks to get results

I've been very happy with the three Vandorens I have (two for tenor, one sop.). If you really want to stay close to a Yamaha 4C opening size, the closest Vandoren would be a T25 or TL4 ('Optimum') V5. If you're willing to stretch yourself just a bit you could go for a T45 Java. It's a bigger opening, but not by that much, and it's more stylistically versatile than the V5 (which is designed for classical). Happy hunting...

Thanks Mark, When you say classical I assume you mean the style and sound of the saz players during the 30's/40's and 50's. A smooth velvet sound. Is that right?

I meant 'classical' as in orchestral. You might want to browse vandoren.com & read their recommendations...
