I've become a big fan of Southwire's "Sim-Pull" products. I've only worked with it myself one time, but it sure looks great and does pull easily just like they say it does.
They offer just about all colors and sizes. The only problem is that many supply houses around here don't stock it. It seems that most orders must be placed in advance and the cable is cut/reeled at the factory, then drop shipped. That adds to the cost and delivery time, but like I said, it sure looks nice.
Not to mention that there is zero room for error as opposed to tape or paint marking.
