Any updates on noise and longevity of the metallic pads and rotors?? I assume you were using the J04C? I've burned through 2 sets of the J02A resin pads in ~2500 miles of mostly dry weather riding and am not looking forward to the wet weather wear if that is any indication of what to expect based on previous disc brakes with resin pads(TRP Spyre/HYRD/BB7). Already using metallics on my SRAM Red race bike and they've lasted for 1.5 seasons after i burned through a set of resin pads in like 2 races but they are a little noisy, and get especially bad in the rain and mud.
