Opinions on "downgrading" sidemount regulators

[Jens Bölte]

Hello,

f my memory is correct the only difference in breathing comes from the tuning of the 2nd stage. That would again make DFC marketing BS. So hard to decide

DFC does not facilitate breathing. It just counteracts the IP-drop when starting to breathe. Your work of breathing is determined by the cracking effort (work needed to open the valve; depends on the spring strength and distance of the poppet seat and the valve) and the breathing resistance (put in simple terms maximal potential opening of the valve).

Best wishes Jens

Noone has mentioned it yet, but, servo assist systems allow for upside down orientation and are way more resistant to free flow. Some folks dislike the feeling of their cracking behavior, I’ve liked it so far.
