3-4 clicks back usually gets in a happy medium spot. Legs to me sometimes seem a bit big in some armours, but I like sleeker legs. I'd recommend dropping it down a few notches. Also has worked well with armors meant for UNP (more generic) little to no issues. Seraphims releaser on xbox (alpineyj) also nice enough to give a plethora of armour mods that won't seam I have found.
Seraphim is what I have used mostly and and I don't get neck seam most of the time.
