DD's Will not be much harder to evade.
They will be looking for you longer after losing contact. 30min instead of 15min.
They will see you better in good weather, and worser in bad.
They will hear you better if you have you engines running anything highter then slow. and even at slow with silent running they will hear you better.
They will also hear you a little farther.
Have Fun
