Good luck, BC! It seems the advice , in summary, is:-
1) Ask why the company has not inhibited the 'climb' RA at 390 if that is what they EXPECT you to do (see post by 'safetypee' on P1 and 'simjock' on P2)
2) Confirm your Company (Ops Manual) REQUIRES you to follow a RA (see 'catchup and 'flapsone' on P1), then back to note 1) and ask why...............
The fact is that 'disobeying' an RA is far more likely to cause an accident than exceeding any particular altitude for a short time (unless the a/c performance is inadequate - see 1), and CERTAINLY manoeuvring AGAINST an RA can be fatal as we sadly saw.
