What are some good items on Sion (Jungle)?

I've been playing a lot of Sion lately, and I'd like to know from some Sion mains what their build normally consists of. Generally, my build goes like this:

Cinderhulk first, Mercs default, Tabis if enemy comp is AA based

Next portion depends on if I'm ahead or behind, and on enemy comp.

Behind: Either deadman's, randuin's, or frozen heart; Visage if AP heavy, occasionally locket or mikael's if they have suppress and our ADC is fed

Ahead: Iceborne + visage or Iceborne + titanic + visage

Every once in awhile I throw in a steraks or a GA if i'm super ahead or if we're teamfighting early.

Is there anything i'm missing, like a hidden gem of an item on Sion? I feel like I have a decent buildpath for most situations.

My most common build is probably Cinder>Mercs>Chainvest>Visage>finish Deadmans>Randuins/Locket>situational
