It's not the line unless the lining is causing the failure - i.e. particles falling off or reacting with the brake fluid?
Longer or softer clutch lines actually help with the reliability of the whole system.
Some race teams will run softer (i.e. rubber, non-braid / non-hard line) on the clutch hydraulics to help minimize the "shock" of the using the clutch pedal - this is especially true on endurance racing.
