The "goat" woven wire comes in a lot of different heights and grid sizes. You'll notice on them that the openings are smaller towards the bottom. They also come in strange heights, since they are most commonly used with a high tensile hotwire along the top. The 330' rolls come in 39", 26", 50", 58", etc.
In my climate, the woven wire does make most sense. Our spring flush creates canary grass which grows to 6'+ in less tham a month. It kills any system relying on hot wires solely. So having the added benefit of the woven wire beneaht the hot wires is truly a barrier.
Then I drive through Nevada and see mile after mile of dry lots where weed growth is never an issue. Their needs would be entirely different from mine.
