FWIW, I've seen advertisements showing
teflon lines with a Kevlar outer braid.
The selling points: The Kevlar outer
braid's strands are less likely to break
than those in the CRES braid and won't
puncture a line if they do. It also
offers a reduction in weight, approx
half of which is unsprung. And, the
Kevlar reinforced lines supposedly
expand less when pressurized, offering a
firmer pedal. Too bad I can't use
them...
