With respect ShockWave and TangoUniform, there's a not so subtle difference between the admirable idea of flying an experienced FO with a new captain and flying an experienced FO with a newly employed direct entry captain who has little or no experience in long haul/wide body/ETOPS/international operations/third world operations (take your [multiple] pick), especially if said DEC is taking the command slot the FO thought might have been his by now.
There's quite a difference between what you both describe and what all too often happens on the line with experienced FOs and some of EK's recent DECs.
