The best large pasture fencing and cost prohibitive is a 7 wire high tensile. I put the T-Post about 20 ft apart and wood post braces at the end. I use inline springs and tightners. I put the insulators about 8inches apart on the t-posts. Lastly, I would put a gallegher 80acre fence charger on the lines. It keeps the goats in and the coyotes out. I tried other fence charges but the New Zealand gallegher goes by acres and not by miles of fence. They do not think about Challenging the fence after the first day. It is the best fence for our mountain terrain. If I lived somewhere flat I would consider the wove wire. Tim in NC
