[D. Scott MacKenzie]

THe Rohn Catalog recommends temporary guys when climbing....but the big
question is - how do you guy the top if you can't climb it?

Hello Ken
       I think you would over load that 40' when you climb it.20 to 30 feet
of 25G is pretty shakey when your on top with no guys.Just my .02 cents.
