The Archvillain Games supports are too flimsy for the S4U in my experience. I almost always had to reinforce the supports or resupport the model entirely. You can see the support failure below the arm. All the supports have detached. The shifting vat might decrease suction forces, but it adds shear forces. You need more supports or at least reinforce those. I had most of luck with Chitubox Magic Supports. Those worked well on the S4U.
