For the F.O. Stormtrooper, if anyone wants... I got one last year, plus intending to get a full-size one once all the options have become consistently reliable for me to compare. But in both cases, I'm going to replace the "frown mesh" with an actual open-cell hexagonal mesh. The only accurate one anyone was able to find was from a company in the U.K. and only available in whole sheets -- four feet by eight feet. I, ah... got one. And had it shipped to me here in the States. I only need about a square foot for all my intended uses, so the rest is up for grabs, should anyone want to upgrade from molded-in detail.
