Good catch!
I am currently playing a UK BICE game and my convoys were getting hit hard in the Bay of Biscay, so that sea zone was in my mind when I wrote that. I had the convoy action on my mind, just the wrong side of it. I will edit my post to so not to confuse others.
make your convoys go trough iceland. There is no point to send convoy by the mid atlantic as UK can afford the DD´s.
This also has the added benefit of avoiding deep sea regions.
You can use Gibraltar with a few factorys on Heavy Planes + DD´s to defend the Iberia + Mediterran!
Don´t know much about black ice but the Air/Sea logic should more or less stay the same.
I always put snorkel instead of radar on my subs in order to decrease sub-visibility.
( Unfortunately the game does not reflect on radar-detecting-sensors...
)
vs AI a SUb III don´t really need snorkels, they never use Cruisers full of Planes to look out for subs.
(But it really helps to keep your sub II alive)
As long the Kill/Death ratio improves its usually worth to lose more equipment.
vs Players i agree Snorkels first, radar only with sub IV`s. as it can get pretty hard to avoid patrols, even in the middle of the ocean.
