Hi, I acquired a Shadow Commander set (only KO though ) and I am looking to get some Perfect Effect Warriors to put on it. First do they still fit on the KO armor, I've heard there were some problems. Second which ones should I get? Should I get two Shadow Warriors (would look nice and symmetrical) or one Shadow Warrior and one Shadow Demolitions (bonus would be the added backpack but they would be different colors). LMK what you all think!!
