Example: "On my Yamaha Xeno it felt centered, a little resistant, and easier above the staff than my 3C."

Example: "Good commercial piece for me: bright response, comfortable rim, but tiring after a long set."

Reference Notes

Inferred from the Hammond audit matrix: rim 4, cup XL, throat #25, backbore #5. Use these measurements as a comparison starting point: fit and response still depend on the player, dental structure, instrument receiver, and each manufacturer's measuring method.
