To give an update, I decide to keep the X4 E's. They are super light and way less bulky than the X4 Pro's. I used the X4 E's last night in a game, and they seemed to work exactly how I was hoping. They stayed in place, and gave some extra cushion to my knees. They felt a little more bulky than my Bauer GSX's, but that is to be expected. I did not take any shots off of them, so I cannot say how the shot protection is on them, but like I said previously, protection from shots is not a huge concern for me.
