L4 too slow

Farm the first mission (not restricted to level 6) hard and you'll get the I-1.

Keep L4 if you love that frontal power, but I prefer to actually get to my opponent first.

Also, immediately equip the last unlocked torpedos. Although they do less damage, they weigh less, allowing for more salvos.

I-1 goes back to 4 frontal torpedos, but has 2 butt torpedos. Once you get there, load the butt torpedos with 2 of the 5000 damage ones for each slot. That way, if a ship tries to tail you, they are in for a surprise.

Ask Wolf about Doc's clutch win.
