We do. Whoever is PF goes on O2 at 350 on the way up and comes off on the way down.

I know lots of guys don't, but that doesn't make it right.

Integrity is doing the right thing when no one is looking. The feds would never know if we used O2 or not above 350 (or 350/410 on part 91 legs as appropriate - one or two pilots on board at the controls), but that doesn't stop us from doing it.
