I don't know where your info comes from, but my Sig Citabria is covered in Coverite fabric and finished with dope. It is by no means heavy, and is one of the best flying Citabria/Decathlons I have ever flown. Yes, it takes skill to build one correctly, but the Sig kit has the right outlines and flies beautifully. Very benign slow flight envelope.
