I've never had a failure of 1" galv poultry/hex/chicken wire. The cheap 2" stuff is another story... the tighter the mesh the stronger it is even at the same gauge.
People claim it's easily ripped by predators, but with a tensile strength of roughly 60lbs for a single strand, I want to know where in Maine there are mountain lions to break through the mesh. It'd take a serious effort by a large predator, but again, the fastening or run itself is likely to fail first. If it's galvanized, its no more prone to rusting than hardware cloth. It's been standard faire for decades for good reason, the internet is just making people paranoid and ready to over spend.
As far as a fastening tip. the best thing I've found to do is sandwich it between two boards using screws. All ours are stapled to a 2x4 to hold in place, and then a piece of strapping is run over the top and fastened by every foot or so pinch and hook the wire a few squares in. A large man could use the side of one of our tractors like a hammock.
Predators that don't care about netting are things that burrow under or come over, so that's a consideration for a permanent run in designing.
