I'm new at this and will begin to fence app. 80 acres with 10 foot tall fencing using 14" posts as required here in Michigan. I'm looking at Stay-Tuff and Bekaert fencing in the 23/120 (23120) style with 6" vertical stays. What are your recomendatons? Also, I've been reading up on posts. WOW. Steel or wood, round or square? Right now I'm leaning toward treated wood. Any suggestions? Thanks.
