This business about standard hoses, don't cars have the same hoses fitted? They are exposed to more road crap than our nice clean standard hoses and they don't get replaced after 5 or 6 years. Im not saying that braided aren't better, but I replace mine if the brake is spongy and ive ruled out master cylinder probs first. Actually, I prefer not to change the rear ones unless they are obviously U.S. My way of thinking is that you use the front brakes with your hand so you have a lot of "feel", and after fitting braided, the amount of movement from off to on is reduced, its almost down to how much pressure you put on them even though the lever doesn't move much. With the rear, you are operating it with a big boot on your foot, so not much "feel" and ive found that the extra "sponginess" of the standard hoses can help with hard braking by avoiding the rear locking up as it would do with the "switch" feel you get with braided.
Not wishing to start an argument here, but as long as standard hoses feel good and work well I don't think they need to be replaced unless you just want the "bling" factor.
