Looks great. Please put an earth anchor in for each row and attach the upper wires to it for lightning protection. Sounds silly, but if lightning strikes and it isn't grounded, it will fry the row of grapes. I will be putting in a few split canopy rows also- I will show what I'm talking about soon. I'm not sure if it has been done like this before, but I'm doing it as part of my training system trial.
