Ensuring correct placement of equipment on characters

[Shotokanguy]

It seems like one complicated area of Skyrim modding can be when you have a bunch of mods to change skeletons and place weapons and clothing and stuff on your character in different ways. I actually tested stuff like Dual Sheath Redux and got it to work fine, but I found that other stuff didn't exactly work out so well, such as backpacks sitting a little low on my character's back.

 

Now I'm also going to try using belt mounted quivers, cloaks, and animations that might require a different skeleton...if there's a mod that might be necessary to make everything go in the right spot and look good, I might not know about it though. For example, STEP recommends using daggers on the back, but I didn't want that. Are there things like that I should use?
