Just taking a guess at the future but I'd say that when the market does start to pick up then they'll be a sudden influx of people learning to fly who were putting it off before due to the market. Doesn't really help you for now but it all depends on your personal circumstances; doubt any low hour fATPL will be getting much other than FI for next couple of years so it depends on if you have a good day job to fall back on. If so maybe do the instructor course when theres signs of the market recovering.
