I have just put 2 piece goodrige lines on from demontweaks, £50 delivered.
The oe setup is 1 line from the master cylinder which splits into 2 lines to the calipers, so thats a 3 lines kit.
The 2 line kit which i have put on, is 2 lines directly from the master cylinder via a double banjo bolt (supplied) to the calipers without the need to be split.
As for bleeding i found it easier to fill the lines back to front, injecting fluid up the line via the caliper bleed screw, so the air was vernted out the top through the open master cylinder.. Worked a treat
