I need a new clarinet mouthpiece

I chipped the tip of the Vandoren M13 Lyre I had (not too bummed out though, I really didn't like that mouthpiece or the sound that much).

I usually use something like a Vandoren 3 1/2 or 4 reed (usually scraped a bit to my liking, so it's probably a bit softer than the number indicates).

Any mouthpiece recommendations? I'm more classical than jazz right now, so I'd like something fairly round, focused, and moderately dark.
