good point plovett.
If you anticipate a career in the shiny metal, some insturcting background may be useful for a career in the heavy metal like check and training. some heavy metal drivers may like to elaborate on this.
Also, of the many "Check and Trainers" around (especially in G.A.) there would seem to be a lot of "checkers" but not too many "trainers." Maybe some instructing background would help to alleviate this.
