I have hung my ATI fixture, and have some spare metal cable. I notice the cable has a nice crimp of sorts on the one end that terminates at the upper mount, but the other end of the cable is just bare. What have you all done to cut off your extra cable? Does the wire fray if you just snip it? Is there somewhere I can get one of these special crimps (I think the cable is aircraft cable; maybe a cessna maintenance shop?)
