I'm switching over to using wire clamps when I can. Don't have to worry any more about keeping lots of sizes on hand, or if they'll hold tight enough, or whether they will rust. I plan to use some electric fence wire that I have, but it 'should' be a bit heavier wire.
Here's a video on those type systems. There are several styles that one can make. I'm working on something slightly different than anything else I've seen. Progress is slow because the mosquitoes are worse this year than I've ever seen, and I don't have a shop to work in. My shop is the great outdoors.https://www.youtube.com/watch?v=mRc7ZDRcgrQ
