Also as most of us would know, the two systems, [reverse thrust & brakes] are different retardation devices which are effective in different speed/landing regimes, reverse being most effective at higher speeds.

There's a more subtle point here though - asking the question about brakes would not apply to the use of reverse. IOW, just because one doesn't use 3000psi on the brakes as a routine action does not mean it is reasonable to say that one shouldn't use full reverse.

The question of flap setting and stability on the approach has been around a while as well, most notably on the A320 and A321, (which have since been addressed by Airbus in terms of damping the aileron response to stick inputs).

Onthe landing flap selection, we dont' know what the crew assessed or decided was the tailwind component they expected to experience. It is likely with a long runway and experience in the approach weather and perhaps with the specific airport, the expectation of a "difficult" approach/landing may have been comparatively low and the selection of landing flap may have been governed accordingly.
