Highly heat efficient, not terribly slow, great weapons layout and Zombie Capability. It gets in and fights, wins, then goes to another fight and wins that one too.
This is basically what I came up with too. My version sacrificed a heatsink and some leg armour for extra ammo, and put the LPL on the arm for better aiming. I don't mind slightly less than max leg armour on non-jumping mechs, as long as both legs still add up to about the same as the CT.
