Yeah, until you get used to how it messes with your weight distribution, it does tend to surprise you the first couple times you put it all on and try to do anything. The changes in center of mass, and the extra weight on your extremities kinda throw you off.
It was humbling for me last night as well. The voiders resist me lifting my arms, and combined with the weight, I was feeling unusually weak when we were doing all the high-guard stuff. As in, I think I need to lift weights regularly to compensate for that. Yikes.
But really, I think your kit is looking great, and the yellow is very striking. Knock em dead!
