Any of the sun control fabrics in gray work well? I saw on that other forum that someone tried the sheerweave 2000 in platinum/white, but no details or measurements. Has anyone made measurements of the platinum color for shearweave products or the plat/white? Any other grey AT options would be appreciated as well (screen innovations has a grey AT weave, but I do not even want to know what it costs... just where they source it!).
