On a formula 40 I was on...the owner replaced the stock tramp with a commercial grade spectra fishing net.
The advantage was: Strong, light, less windage, easy to repair. As it was a 'net' you could not rip it....HOWEVER....if you dropped something small...say goodbye....a couple of cell phones...and a shoe were victim once....other than that...it was great. Another advantage is that you can weave the bitter ends of the sheets thru the net...always keeps the 'deck' clear...
maybe an idea for you?
