I've heard a few times that Chain link fencing with "hedge link" slats is the best fence bang for the buck for fencing for long term. But I'm not made of that $ to know...
Depending on location, And how old you are or plan to live there. My stained wood fence lasted about 15 years now and it needs replaced fairly soon if not yesterday.
And Leland cypress grows out of hand in about the 6th or 8th year. And it burns like crazy! I had to cut a row down once.
I was also given the best advise from a kid waiting in line in front of me when I too took a baggie of soil sample into my local college. I mentioned that I had one, then another, then another die. He looked me in the eye and said "then why don't you just plant something else".
I've never felt so stupid to have dug a baggie of dirt to have driven to be waiting in a line in my life as I patted him on the back and left.
That's when I pulled an extra Leland up in both directions from the ones that died and planted "Wax Leaf Ligustrum" in that area. Wished I'd planted that from the start.
Soule88, I think the distance from the line is relative to how comfortable you are with the neighbor, how much cheap vodka you buy and how much future shit you are ready to take from your neighbor or future neighbors. My neighbor was close to just being asked for a gun dual to get the misery over with so mine went like 1" off the line if that and she couldn't say nothing.
I lucked out and now have cool neighbors. 8"-12" sounds ideal to me.
