You wouldn't get me up 40 foot of that stuff without guys.  The third 
section goes up with guys even if temporary, but typically I prefer 
temporary guys take the abuse of assembly and then be replaced with new, 
permanent guys. After the 3rd section every section goes up with 
temporary guys attached.  I make it a rule never to climb above the last 
set of guys except to stand on top.
