You should add the Harder escorts that comes with TMO.
What ever you may think none of the TMO escorts are as hard as running Operation Monsun and coming up against British escorts. Hands down that mod has the hardest escorts of all.
I love the challenge that TMO and RFB have with RSRD but their escorts are easy compared to Operation Monsun. The longest depth charge attack I have ever ran into was in Operation Monsun ... it went about 36 hours straight. In TMO I have never had an attack go more than about 5 hours. The Japanese have little in the way of good ASW. They also did not have Hedgehogs like the British and Americans ... I hate those things.
