If your local store sells it, I suggest a T, or Ted, or Theodore Johnson mouthpiece
I broke my mouthpiece three times and I kept getting that one
It sells for about $26 where I am
And it's designed by one of the best clarinetests in the world
But I can totally feel you for breaking your mouthpiece
I was a klutz last year and did it twice in a month or so
And then it fell off the bleachers at a football game this year
