Type VIIB or Type VIIC?

I ran some tests in Gibraltar port where I found a docked destroyer (that kept pinging me but couldn't move ). At close distance, both impact and magnetic torpedoes failed to detonate. But if distance was more than 300m, magnetic torpedo worked flawlessly. So I was probably just firing at ships too close. Therefore I extended my prefered range to 400m-1000m.

Thanks, I will keep the VIIB until the end of 1941 due to its greater speed, and then upgrade. In the middle of 1941 VIIC is not so advantageous. I would also like to try IX at some point maybe in 1943-1944.
