Well, did the math. Swapping the 200 Compact with a 400 XXL, dropping 1 ton of ammo and one of the torso rifles, then moving another to the CT loses 4 tons on the gyro, 4.5 tons on the engine but still allows 11.5 more tons of armor. Going with Hardened only gives 276 points of hardened armor, not enough to bother except for the crit resistance. Staying with Clan Ferro provides too much armor (chassis supports 600, Clan Ferro would be 661 or so). Oddly enough, you could drop what clan gear I did put on, since IS Ferro gives exactly 600 (well, 600.32, but round down), and since the engine’s big enough to hide the heat sinks the Compact 200 couldn’t, you no longer have to rely on the Shark Foxes for resupplies.
