The Katana Kat is something that I've been using for the one AI pilot in the smallest mech for a little while now. Put a pilot with decent defense and good energy skills in a KK with PPC's and a little LRM5, and they'll be an okay support pilot shooting down VTols, tanks, etc., while avoiding a lot of damage. I just managed to find another Katana Kat last night, so bought it as a backup, setting it up with the same loadout. I feel this is better than using a Jenner or whatever.
