So what I can take from your post is:
a) You think there is no gain in paying for your own TR
b) If line training is offered along with a TR course then that would be most benefitial.
c) TR's centre on flight operations and proceedures in the specific aircraft rather than on teaching flying, it is assumed that you should be able to handle a heavy aircraft with adequate skill without additional instruction.
d) Job prospects aren't too good with minimums even with a valid TR.
e) You think it is folly to consider A330/B767
f) You need to visit the A&E at Bristol Royal Infirmary
As I said before, so often I'll be here for a while copy and pasting examples, I'm not dead set, I am doing research to see if its viable and would aid the career at this point. However I don't feel the hearty distain for suggesting such a path that has been levelled against me is wholly justified.
