Yep I would always recommend hollowing all but the smallest of models. It sounds like what's happened is that the suction forces have pulled the model away from the contact points. Reducing the lift speed has a similar effect - do both and you can go with surprising thin supports and hairlike detail. This is 1/144 scale and I've boosted the detail to allow for safer handling when gaming, but I think this shows what you can achieve - you can actually go finer than this.
