I'm playing around with this stuff today. I bought the 25# wire at Bass Pro, and I also picked up some Malin single barrel sleeves. The wire is 0.014" and the sleeves are 0.033", so doubling the wire back through the sleeves leaves only .005".

I found that doubling the wire back through the sleeves was easy and clean. I could leave a nice small loop and crimp it down nicely. It felt good in hand, although I used some paracord to hang a 15# kettle bell and one crimp did fail - the wire backed out.

I am trying to tie some and finding that much more difficult; I've not made one good knot yet. I'm starting to wonder if I could crimp them down, and then tie off the tag end behind the crimp…

Anyway, I am hoping to test both crimped and tied models next week - assuming that I can get one tied.  ;D
