03 HOW TO CHOOSE

Choose by feel, confirm by sample.

The fill is best judged in hand, not from a description.

A gel fill gives a heavy slow squeeze, beads give a crisp crunch, and clay offers a firm moldable feel. The only reliable way to choose is a physical sample — confirm the fill, recovery and sound response against your brief before production.
