STA for me, even with the DGX wing. Before I bought it I confirmed it would work with an STA. DGX tried to sell me on not using one, but confirmed it would work with one. Given that I use 2 different plates, 2 different STAs, and 3 different wings based upon my tank & exposure suit combinations, NOT using an STA is a PITA. The STA gives me the flexibility to mix & match as needed on any dive.
I too also find an STA setup more stable. Yes, I’ve used both. Others disagree as you’re seeing. We all agree to disagree. You need to make the decision based upon what works best for you.
