Thanks for all the responses here from folks. Lots to think about. Looks like I'll do my best to keep straight lines, and will use double 45deg "corners" to ease out the sharp edges.
Just learned from the fencing contractor they use 5" line and corner posts but 6" gate posts. It's easy to spend other people's money, but would y'all be concerned about 5" corner posts, and would you recommend upgrading to 6"?. RedBrand and StayTuff seem to recommend 6"+ corner posts.
