Why? It's much easier to bend your own lines, using copper-nickel, than it is to screw with "perfect-fitting" "custom" lines from any manufacturer.
Think about how much more you want to mess with these, and if its not much, just cut your losses, buy some line and some nuts, do it yourself, and do it right.
Kit came highly recommended so I went that direction. I can do a little tube work but the amount I would need to do from scratch is a no-go with my old hand injuries.
