I wouldn't mind if such fins--plexiglass and waferglass fins are not uncommon on competition rockets--were offered in "regular" kits. (I once had--but never got around to building--one or two of the "pre-Tim Milligan era" [it was the Ed LaCroix era; he started the company] Apogee Components streamer duration rocket kits [see: http://www.ninfinger.org/rockets/ca...4apogeecat.html ], which had phenolic body tubes and thin waferglass fins, which were very thin and smooth.) Also:

When I visited the Northcote Heavy Horse Centre in England for a couple of weeks in August of 2010, Stuart Lodge, a long-time British competition spacemodeler and contest judge, came to visit me there one day. He brought along a packing case full of models that he has flown in contests all over the world (they appear in several of his books). They include a scale Vertikal vehicle (whose spherical nose/separable instrument capsule [on the actual vehicle] is depicted by a glass sphere bottle [for perfume or cologne, if memory serves]) and an MMI Aerobee-Hi, whose fins appear to be made of waferglass or plexiglass (they're very light, thin, and stiff, yet very smoothly-finished).
