Thanks. I'll be moving mine from the North end of the yard where my pecan trees are in the Fall to the South end around the garden in the Spring. Lighter ga makes sense.Yup it's the electricity that stops the deer, lighter wire is easier to work with. I don't recall what ga. I use but it's thin and flexible. I've had the same roll for years and I am always cutting and splicing it for different configurations. The heavy stuff is great for permanent fencing but pick mine up in the fall and put it back up when things begin to grow in the spring.
