You might want to look at braided lines by Goodridge which are available from Lockhart Pillips.
Also check out the snippit on braided break lines on the premier issue of Super Street Bike (which just hit newsstands) on page 33.
Now I don't know shit about braided break lines but I hear you can get them with or without a protective outer coating. I would think the ones with the coatign would be better, but I don't know.
