I play on a Callet. It has a nice cushion, and it's not too deep not too shallow. it's perfect for me. It has to be because over half of my show this year is above high c. I split my lip in Buffalo two years ago, so I had to get a cushioned mouthpiece that i wouldn't split it open on again, and it has paid off. I'm hitting notes i never could before, and my tone has improved drastically.
