I have to agree with your comment about 2 engine missed approaches, Rat5. What's even more surprising is how many pax react to them as some sort of major emergency. (See any TV news report or newspaper article interviewing passengers after a go around.) It really was necessary to make a reassuring PA as soon as possible. On ultra long haul, where I had an extra crew in the jump seats, I would usually ask the other captain to make that all important PA quite early in the missed approach.
I've been extra crew (on ultra long haul) in the jump seat and witnessed almost frightening performance by usually quite competent colleagues in that manoeuvre. Before it was banned, (where the company insisted the procedure be done exactly 'by the book' using the highest level of automation available, which almost always resulted in a rushed procedure that was almost chaotic with 'hands all over the place' as you attempted to cover everything required with the aircraft rocketing towards the usually quite low missed approach altitude), I had my own procedure - after the initial climb was assured, I would take the aircraft out of TOGA and select a vertical speed of 1000fpm. This slowed everything down and made the whole procedure infinitely easier - and more comfortable - for all concerned, and much like a heavy or 'assumed temperature' take off.
This also made the reduction of power on reaching the missed approach altitude less extreme and so didn't freak the pax as much.
