Lisa,
You are right, Stans and Gongoras need more humidity, pure bark isn't a good choice.
Wire baskets are fine, mainly for Stans; if I have some, I use tree fern fiber in the bottom of the basket, then fill with "mixed media" (in my case an ad-mixture of coconut chips, carcoal, pine bark, pine cone and a little of tree fern fiber), and fix the plant with tree fern fiber, covering the upper surface.
In Brazil tree fern fiber became an 'ecological problem' and now its use is forbiden; if I don't have tree fern, I use sphagnum in the place of it; the objective is to make a kind of 'envelope' around the media, to preserve humidity.
