No not mixing torpedoes just using the standard loadout.
I've been on my next patrol now just arrived on station, on the way had good weather so the 4 merchants I attacked were with deck guns. Still early war so they aren't armed yet.
At the moment I am lying in wait ahead of a convoy with a destroyer way out front and one way in the rear but none flanking the convoy. This will be a longer distance shot so I guess we will see if I score any hits
