Are both Balanced armor enhancement legal in PFS?

[Michael Haneline]

I noticed that there are two completely different armor enhancements named "Balanced", one from Ultimate Equipment in 2012, and one from Armor Master's Handbook in 2016.

The one from Ultimate Equipment gives a bonus to CMD and acrobatics checks. The one from Armor Master's Handbook lets you move your armor's enhancement bonus to AC to a single saving throw as an immediate action.

Both sources are PFS legal. Does this mean you can have a +1 Balanced Balanced Breastplate? Or is only the one from AMH considered legal as it is the most recent book and is therefore considered an "update" of the one in UE?

[Wei Ji the Learner]

Splatbooks usually don't supersede hardcovers.

So I'm imagining yes, you'd have a +1 Balanced(UE) Balanced(AMH) breastplate, for all the Zen armor needs.
