As a general rule, don't take druid advice from trickshittr.
SoP adds +50 life and max fire/light res, which makes it better than spirit against everything except possibly blizz sorcs (and even then, really, its better)
The max block setup is optional and not necessarily helpful. If you want it, then do it. Its your char. In most of your "I need block" matchups you would probably be better off hitting the fcr bp instead.
Your swaps would probably be something like
wizardspike
pelt
resist stack circlet
dungo's
bloodfist(maybe?)
raven raven
wisp wisp
dwarf dwarf
tgods
crafted rep boots
That's only about half of your stash space. I put fuck-around toys in the leftover spots. Doom, marrowwalk, widowmaker, a beastz for buffing my merc, demonlimb. I don't think any of them ever won a duel for me besides the bone prison charges.
I think you'll find that you never want to put the mb setup on and it just takes up space in stash.
