      Cup Diameter

      The Curry 12C has a cup diameter of 24.23 mm / 0.9540 in compared to 22.99 mm / 0.9051 in on the Schilke 42B — a difference of 1.24 mm / 0.0489 in. A wider cup generally produces a fuller, darker tone but requires more air support.

      Cup Depth

      Both mouthpieces share a medium cup depth, so the sound character from depth alone will be very similar.

      Throat Diameter

      The Schilke 42B has a wider throat (5.95 mm / 0.2343 in vs 5.92 mm / 0.2330 in). A wider throat allows more air through, increasing volume and projection but reducing resistance.

      Which is better?

      Neither mouthpiece clearly dominates the other — the right choice depends on your embouchure, playing style, and the sound you're after. Try both if possible.
