      Cup Diameter

      The Curry 128G has a cup diameter of 32.51 mm / 1.2800 in compared to 32.50 mm / 1.2795 in on the Bruno Tilz 231-C 3 — a difference of 0.01 mm / 0.0005 in. A wider cup generally produces a fuller, darker tone but requires more air support.

      Cup Depth

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

      Throat Diameter

      The Curry 128G has a wider throat (8.18 mm / 0.3220 in vs 8.00 mm / 0.3150 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.
