“I've been using 16 gauge spider wire for several years. I use it with G springs, plugs and inserts, along with a tension spring and attach it to 3/8 fiberglass posts with a metal u clip. My ranch is rough and rocky and the smaller posts and wire are much easier to deal with and very flexible allowing deer and elk to get thru it without tearing it up. Also I use only a 4" top x 6.5' wood post buried 3' for the end post, which really saves on labor. I graze sheep and cattle, so two wires are put up. I probably have over 15 miles of this fence. I do replace several 3/8 posts each year that break at ground level. I use kiwi poly wire to make subdivisions when needed.”
