Downloaded these a little while back and played around with them both then and today. I'm not entirely sure if I like that they use T+T, but I know that's something you're still deciding yourself. The models are awesome and I love using them in-game.
It's been stated already but ammo doesn't seem to work with these. I'm not sure if it's related, but some of the weapons are also QQ-able (I know the flamer is, and I think the plasma guns are too). There's also the possibility that you've updated the download link and I still have the version from a week or two ago.
