I use 'em about like Warhawk does; to finish off merchines I foolishly only put two bow torpedos into. Still not used to the smaller US warhead sizes....while I greatly prefer the USN's submarines to the Kriegsmarine's, a year or two on SH III has left me envious of the bigger kaboom the German fish pack.
Sometimes if you get inside a convoy, they're great for some all 'round destruction. If you use manual targetting (unlike me), just let 'em get within 400 yards.
Solution? Bah! Who needs one?
