I have the armors but have noticed a couple of aesthetic problems.
1. When you use the Rank4 Heavy MG with Predator armor, the soldier becomes invisible - so there may be some sprite problem happening there.
2. When equipping the new variations of Predator Armor - I noticed that the model displayed is reversed between the hero and seeker from what is in the Xenopedia descriptions. I'm not sure which one you intended to have the cape, but I would just advice making sure that they match. The stats seemed to - Hero improved Bravery - Seeker improved health. It was just the appearance that seemed inconsistent.
3. Slightly minor - with both of the above models, the changes to health cause the Wounded + a Percentage to appear on my soldiers. Not sure if there is a way around that or not.
These are some minor deals - I honestly consider your mod(s) my favorite and I love how much effort you put into support. Just created an account so I could let you know about this stuff.
