Get us some before and after pics ZYBAN? And how they perform? And what extra bits did you need to get? Like, some new lines or anything? Or just swap out the bits you get from walka?

I would also be interested in seeing how they go. The front brakes on my 2009 XL1200C are gash

If they are their own pads, what do the pads cost, and what pad options are there?

They use the same pads as Willwood, HHI and Rev Tec,, $35.00 A SET

 can you use them on a 2011 nightster walka?

There only 1987 to 1999 , For 2000 and up I have HHI 4 Pistons in Chrome only $299.00

WIL150-8733 $35.00 A PAIR, You haven't gone though a set of Pads in one Week Zyban?

ZYBAN - did you put them on yourself? What did it involve? Are there fluids and what-not? Is it just a straight swap with the original ones? Did you do the back ones too?
