HOW DEEP WOULD YOU GO ON AIR while SOLO DIVING IN A CAVE?

[speleocrone]

48m (that's metres for you guys) is it for me but I'm not that comfortable with it so everything else needs to be on side; good vis, not cold, not much exertion, familiar cave, easy cave, built up depth over recent dives...

I am comfortable at 40m.

Twenty five years ago when I knew no better I did a few air dives to 68M. Now 40M is enough.
