I've yet to encounter these uber escorts (using TW2.0). Once using RuB I got jumped by a flock of black swans, in late 44, in perfect weather, and had to use all my decoys, and every devious tactic to evade them. I lucked out on the coin toss and I made it. Another similar close call happened in my old favourite VIIB; more BS and close depth charges, seemingly no escape. But finally, with enough careful listening on the hydrophone, decoys and flank bursts, I made it.
But I've heard a lot about uber escorts...just can't vouch for it myself.
My new approach is to attack the escorts directly - my first attack on a convoy sinks the lead escort so I always have a way in. On my first exit (through the back) I attack the rear escort at zero gyro, knife-fight range. Seems to work pretty well. I'm sick of running from these b*stards - it's totally satisfying to reduce a convoy to a single escort (or better, none!). You can almost always escape a single escort with careful work.
