I've been struggling to setup my SA TA and SATA parts.
I've looked at quite a few gearswaps and tinkered with it but without any luck.

I'm trying to get my SA gear equipped when SA is active / TA equipped when TA is active / and my SA and TA equipped when both are active.
The best I've done so far is to get it to equip at precast but it immediately swaps back to my TP / Idle set depending on engage.
