Meh. Properly bleeding your brakes will do more for pedal feel than stainless braided lines. I run rubber hoses on my street cars and save the braided stuff for actual race cars. If you do go with braided lines, you absolutely have to secure the brake lines so they can't possibly rub on your tires.
The problem is that the GMT800 master cylinder feels great right up until you have to make an emergency stop, and can't.
