Beware of the bulk wire with the clear sheath sold by B&M retailers like Home Depot or Lowes IF you plan on running this stuff in an attic. After about 10 years or so in my attic, the copper discolored and started to turn green in places. I guess a combination of the rubber reacting with the copper plus running it up into attic caused the wire to go bad.
If you are going in-wall to attic or crawl space, then get CL2/CL3 rated wire. Now I use CL2/CL3 rated wire for ALL of my wire since it has a nice, round sheath that looks really professional when covered with TechFlex. There is a whole thread on how to make your own cables.
