    The easiest thing is to use one PreForm as a temporary and then 
just throw it away when you're done. Just hook the comealong to it -
you don't have to wrap it the whole way.

    The aforementioned Klein cable grip is a good method (they're available
at I have 3 and 3 comealongs so have one on each guy -
then it's pretty easy to pull the tower into plumb.

    Sounds like more work than it's worth IMO. You only need to plumb at the 
points. Once the guys are attached, have the climber on the tower use a common 
on the leg to direct the ground crew how much to click the comealong or turn 
turnbuckle to get it plumb. 

    Once you've got the first set of guys on, sight up the tower face. Any tower
lean will be obvious. You can then plumb the tower from the ground or use a 

    A guyed tower can be out three inches in 100 feet and still be within spec 
so you
don't have to get it *exactly* plumb.
