LOL, now you have me confused. What was galvanized, the pole or the wire? How many guy wires did you use and where did you attach them? I would suggest using at least 6 and attach them within a foot of the top of the tree. The lower you mount them, the more leverage the wind has over them and if you use less than 5, there will be wind directions where only 1 wire is handling the entire load. Put these two conditions together and you have a significant point of failure.
