If I understand what I've read correctly, this is a trade-off.  If you 
don't tension to spec, the guy will sag more than it should (because of its 
weight).  Then the tower will move more than it should in the wind, because 
the first thing the wind does is take out the slack, before it starts 
actually to stretch the guy.

On the other hand, if you apply the 670 lb., there will be a little more 
compressive force on the tower before the wind ever blows, though that's 
unlikely to be an issue except under extreme wind conditions where the 
tower approaches its structural limits.

99 percent of the time, I'm sure it will never matter.  But at least we're 
back talking about towers.
