I've been using "SEVENSTRAND" fishing leader line available from larger fishing stores. (Pro-Bass here in Cincinnati) It's stainless, very small and light and has a 90# test. You can get the A-3 ferrules also and make your own snares. I make mine with a loop at both ends, one of which has a fishing swivel attached. Combination seems to be very strong in testing with mechanicals, though have never tested it on anything live! 30ft costs about $3.
