Not a Trieste hater, but the diaphragm is poorly shaped for best performance. It is a dome, one of the structurally strongest shape. As such, it doesn't react to inhaling, lever activation as well as the diaphragm on most other double hose regulators. The overall design is fine, except for the diaphragm. We have taken the "guts" and installed them in USD cans or one of Rob's plastic ones and it works fine. Luis did this years ago with the Voit MR-12 first stage, same as the Trieste minus the second stage and called it the Pegasus.
I am glad yours is a fine breather. Most, in original configuration, are not.
What helps me with it ,is using a new silicon diapragm from Rob and a HPR 2nd stage.
