The market for pilots is recovering really fast by now
According to some accounts...
I am afraid that the market in 4 years is broken again and I won`t get a job.
TBH even if you go straight for the frozen ATPL now the market for pilots could be just as broken in 2 years and you won't get a job. In fact get a repeat of 9/11 and the market for pilots could be broken next week.
There's no correct answer to your question since you'll only know if what you did was right or wrong with hindsight .what I would say is IMHO hopefully the B.Eng at least helps gives you other options should the flying not work out, for whatever reason.
Good Luck anyway, whatever your decision.
