Fiberglass vs. Fabric

Well, maybe no sense right away, but the plans where drawn quite a
while ago. Like the Emeraude, the invention of fiberglass hadn't
arrived yet. Although I agree with the statement of making it as light
as possible, one of the reason's for this post is to discuss weight.
If this can be done with little or no weight penalty, then I thought I
would consider the experimental part of this group. After all, if Tony
Bingelis did it with good results, then why not consider it? I like the
idea of smoother, flatter, and more solid wings. If it turns out to be
25lbs or more, then I have to re-think this or just consider going on a
diet.
