I'm a big fan of the Blood of Kerensky Trilogy and the Twilight of the Clans.  Warrior Trilogy was good as well, though I would like to find out the weapons layout on Legend Killer, the Rifleman that Gray Noton piloted when he was Champion of Solaris VII.  Rifleman is not known as a good Mech to Mech fighter, though the upgraded model with the twin LB-10X Autocannons is very nice.  May have to customize one and see what happens.
