I'm used to climbing 100' of 45G guyed with 6000# test Phillystran which 
is rock steady in a 20 or 30 MPH wind. I have 40' of a 50' 25G up. It's 
bracketed at the roof line and guyed with 5/16" synthetic temporary 
lines. just below 40' and at 30'.  Technically it could go that high 
without guys.  I find it to be "unsteady" at 40 feet with guys on a calm 
day. No way would I climb 40' of the stuff unguyed, let alone more.

The top section is ready to raise, has the guy brackets in place, and 
all I have left to do is calculate the lengths of the Phillystran guys 
and prepare them.

Call me chicken if you'd like, but I've been climbing for over 50 years 
and have never once gotten hurt on a climb.

We used to live a few hundred yards West of a commercial tower.  I had 
permission to climb it as I often worked on it. Many an evening I'd go 
up that thing just to shoot photos of the sunsets.  I like to climb and 
I like to fly aerobatics, but I do not like to take unnecessary chances.
