@A330ETOPS: Your main point is that a TR helps. However, you just said yourself, you got it 6 months ago, and ever since that, you only got 4 interviews, and 2 real possibilities, which are P2F. That's pretty much where anyone with 200 hours is right now (EJ for example), so your TR didnt help at all, just wanted another huge pile of cash.
Another? Yes. The main thing I got out of your message is that you spent 100K GBP getting cpl/ir/me, because you went for the fancy integrated course... You can get the same stuff for about half of that amount. So at the end of the day, its 50K vs. 120K, and we're still exactly in the same shoe. People should not do TRs OR integrated craps.
