Open Throat, or open Backbore?

Looking back through your original post, it reminds me of a CG Personal. I'm playing a variant of that now and what you describe is what it gives me, including the physical sensation you described. Keep in mind that it has a 22 drill throat.

I am sure you will get a lot of well-substantiated responses about opening throat, backbore or incrementing size in rim or cup. These components can certainly accomplish what you are looking for. My 2 cents would be to consider a slightly heavier blank while going bigger on any component mentioned above. You don't need to go all the way to Megatone/Monette style blanks but even a few grams really make a difference.

For example, Yamaha mouthpieces are a tiny bit heavier than Bachs and to me, they certainly feel like they can take more air and don't back up on me as much, especially in the upper register. You can barely tell that there is a difference in Bach and Yamaha blanks.

Since Matt Frost works on your mouthpieces, I am sure he will be open to adding a little extra weight to the blank to balance any other modification you decide to perform on your mouthpiece. This usually adds stability. In my experience, the rule of thumb is that if you increase the size of any component of the mouthpiece (throat, backbore, rim, cup), the mouthpiece does benefit from a heavier blank, even if that's 0.5gr.

Good luck in your journey!
