Visit your local dump, they often have reams of used cable. The best cable is elevator cable that when it reaches a certain # of hours it gets changed out, but is perfect for mainline cable, 9/16" comes to mind or 1/2". It's strong and very high quality and quite flexible too.

Yep, cranes and elevators will dispose of their cable before it is ever even close to being a safety hazard. If you have a friend in eiether one of the businesses buy him some beer and ask for some cable! What you will get will be alot stronger and easier to work with than the stuff from the hardware store.
We have a 5/8 that came off a crane and we moved alot of wood with that cable and a 1450 case dozer (60,000 lb dozer). It has since seen it's demise but we were pretty hard on it and it actually was rubbing a rock on one of the pulls and that is what done it in.
If you want lighter, faster, and more expensive than look into synthetic winch rope. The stuff is so light it will float and extremely strong. The drawbacks are not very abrasion or chemical resistant and UV rays will affect it after extended periods. We put it on a winch at the firehouse and it was impressive and it is alot safer because of its low weight the potential energy stored in it is very little if it breaks.
