What's "deep air"? I've been to 130 on air. That was my first dive trip to Maui, before I knew better.
Now I don't dive air, period, let alone deep.

I'll dive air in the pool ... for everything else there's nitrox.
Locally, my max depth without helium is about 120 fsw.

Done a few 200 foot air dives in Cayman. Look forward to doing it again.
200 feet and a bottom time of 15 minutes is my limit, to reduce O2 exposure. Always had doubles/sidemount and 2 deco tanks.
In the event of a problem,or the slightest suspicion of a problem, or any current,or anything at all just not feeling quite right,plan is to ascend to ~120 and sort it out.
I can feel the narcosis for sure,but I can function well enough to monitor depth,time and pressure. I'm under no illusions I could fix something complicated which is why I like sidemount. (losing gas from somewhere? just ascend ,no need to think,no chance of losing all gas)

I've been badly narced from 130-150 feet. I don't like the feeling and don't like my response time so I won't dive that any more.

Deepest dive yet was to 41msw on air in the Mediterranean. Plan on doing AN/DP and possibly Extended Range in addition to Trimix education.

I've done it, I'm a bit uncomfortable about it and I'd do it again for deep shark cleaning stations. I'd want some buildup and a fair bit of redundancy. I was in Honiara for 4 months this year and I which I'd made it out to see those sharks.

I would do 150 on air back in my younger days spearfishing on the Gulf oil rigs. Many of my buddies routinely did 200. Now at 69 years old I try to keep it above 100 but something may one day lure me deeper.
I used to dive air down to a max depth of 200 fsw. It was for a film project I was working on and I continued it for a little over a year. Once I was through with that project, the deepest I've gone on air was 151 fsw. Since I no longer routinely dive to depths of 180-200 fsw, I now get very noticeably narc'ed at 150 fsw. Back when I dove deep frequently, narcosis was a minor issue.
