I'm not sure I understand why you hate the triangle so much, all it does is indicate weather your torp officer has a good solution or not. I DO have mixed feelings about auto-target, but if you're careful you can get a hit almost every time.

Always open your selected tube door before you do your final pre-fire lock, the door not being open increases the firing time of the torpedo and as your torpedo uses the tracking data at the instant the fire button is pressed (OM), or in the original game the solution at the time the 'lock' button is pressed the time lag created by the outer doors opening increases the chance of a miss.

Always have your rudder centered before you do your final per-fire lockon as the torp fires with the solution (above paragraph) at the time the fire button is pressed. If you're creative you can use the door lag and a quick rudder deflection to 'refine' the torp's destination without altering the TDC solution.

Try to refrain from firing until the triangle indicates a good solution (green triangle) the normally appears only with 20 deg arc directly ahead or astern of the sub.

Auto-target can be your friend if you don't fall into the trap of thinking it's idiot-proof. The majority of my early auto-target shots were misses until I got the timing figured out, now it almost never misses. Just before you're ready to fire (20 sec or so) open your selected tubes outer door, and within 5 seconds of firing- pop up the scope, lock-on, FIRE ! I usually drop the scope, go flank and turn 20 deg ahead of the target (to ensure I can send a follow-up shot if needed) and slow again when I'm pointed ahead of the target.
