I know a guy who worked with carbon fiber lines--Keith Stewart, in
Southern England, in the early 1980's. Beastly expensive at the time. He
said the worst problem was tangles; any small tangle or knot would break
the line. Keith never mentioned abrasive failure of the line, but I
suspect he never used it enough to wear it out.
Spectra is so light, and so strong, and so slippery (and relatively
inexpensive), I doubt carbon's problems will outweigh Spectra's advantages
anytime soon. BTW, don't forget that carbon fiber has *very* low
resistance to electricity--it doens't neeed to be stormy for there to be a
strong voltage between air at 100 ft, and your hands...
