It looks like I can use a 1-Post Wire Rope Clip Cable Clamp instead. Then I don't need a swaging tool.

And now I'm thinking maybe I can use a kevlar braided cord instead of a metal braided rope. For example, here is a 1.7mm diameter one: http://www.amazon.com/gp/product/B00746VAU2

I couldn't agree more on having something like paracord. I also wrap about 6 feet of duct tape on itself (so its small). However, on the paracord issue I have found something that I think is better.

this stuff is great and lighter and its also much thinner and more concealable for traps and boundary warnings.

Did you know that if you eat asparagus and pee in the water, fish will be attracted to it.
