Since Shapeways "restructured" their pricing back in the spring, I have turned to "Strong and Flexible" as the default material for all new models. It is tough and takes paint well and the textured surface seems to suit models of the fabric covered originals very well! Some smaller items will still be in the "Frosted Detail" material as and when the subject demands it, as indeed will all of my flying boats. But as time goes on I will try to introduce more affordable "Strong and Flexible" versions of the majority of my airship subjects.
