Seeing posts about getting some of the major weapon packs to work with TTW which I hope to see come about. In the meantime I'm using New Vegas Ordnance by Z06Frank. It's not as large as some of the others but offers a fairly rounded selection of ballistic weapons including replacers with full NPC integration, ammo and mods. Doesn't appear to require any kind of conversion and even includes a module with a few guns especially FOR TTW. If you want to check it out you can find it at http://www.moddb.com/mods/vegas-ordnance
