I have a Nomad C with an RP23, 13st all in, was blowing through it’s travel too easily, ended up putting the mid-sized air volume spacer in which sorted it.
I have the CCDB Air on a Yeti 303RDH, after a warranty return (was leaking oil through the compression/rebound adjusters) the shock has been excellent. Didn’t stray too far from initial base settings.
