You may be talking about the same stuff, but WalMart (as well as any good sports shop) carrys a small diameter nylon coated seven stranded wire fishing leader material called, clevely enough, "Sevenstrand" that comes in several different strengths, and has sleeves made specifically for crimping the wire... pretty cheap, too... Bought some 27# and 60# for doing pull pull experimentation and for tail bracing...

Cheers!
