Well several of these, the combo regulator/bc inflators, have very good breathing (atomic is one). If you believe Rodels at least three are good enough for serious work at depths of 165 ft. Still there are several considerations..
1 YOU will breath from the combo, the hose is too short for anything else. You and your buddy should clear that if you need to, you will donate your primary
2 Bouyency control, while breathing on the thing is more difficult than with a octo. Not really difficult but a skill that you should learn before you need it. If youy do not have a shoulder deflator, and must deflate using the combo, you may need to take it out of your mouth. You do not want to inhale and operate the BC inflator at the same time.
3 Some of them have buttons designed with out consideration for their use. They are hard to work.
I prefer an octo. I have dove with several buddies that used them and they seemed to work find.
I have seen some tech (maybe) divers use them when they desired an alternate regulator on the left post of a doubles rig. Particularly for divers using isolated doubles. These guys had 4 second stages (two on the left tank and two on the right). One of the combos really seemed to help.
