The concern over braided flex lines lies in the fact that
the braided housing allows intrusion of abrasive particles
into the fluid carrying hosing. The kevlar lined lines, btw
the braid and the teflon hose DOES NOT, IMHO protect well
against this. The clear (of course, so that you can show
off your braided lines) covered lines are MUCH better in
concept, IMHO. Choose lines that cover the Outside of the braid,
and replace every two or so years on a street driven car.
That's the risk of braided lines, although they generally
improve pedal feel.

HTH, sorry not to individually post, got to go teach class....
