      Cup Diameter

      The Curry 7C has a cup diameter of 24.74 mm / 0.9740 in compared to 24.50 mm / 0.9646 in on the Denis Wick 12CS — a difference of 0.24 mm / 0.0094 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 Denis Wick 12CS has a wider throat (6.10 mm / 0.2402 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.
