Give it some time. Skyrim's record structure has not been decoded completely yet.
Much less necessary now, but give it a year and you won't be able to play a modded Skyrim without Wrye Bash.
Oh yeah, I have no doubt, but since the poster is asking a question in the present, I think it's fair to say Bash is currently optional.
Thanks for the tips guys!
I'm also using Dawnguard if that matters at all.
I may look into it but I was hoping the bashed patch wouldn't be necessary.
Dawnguard shouldn't effect your need for it at all. If you think you're going to continue adding armour and weapon mods (and creature mods and all that fun stuff) to the game in the future, I'd encourage you to get Wrye bash now (especially since it uses an easy installer these days), but if the mods you listed are really the only content you're adding, I think you could survive without it. That said, there's a chance a lot of NPC's will spawn with cloaks but no new armor or vice versa, but If that happens you can always just download Bash at a later time.
