I suppose my problem was that my tower is going up and down twice a day 
about 5 days a week ( I always leave my tower nested) so the wire rope is 
rolling over the sheaves all the time, and its was not obvious what the 
difference is if it stops on a sheave.

My desire is not to be "nit-picky" here, but I own one of these and I don't 
want a failure.
The practicality of stopping the tower up, and down, in a different spot all 
the time is a bit challenging to say the least for me (twice a day, 5 days a 
week).
I suppose I'm also somewhat confounded about why, if this were a problem, US 
tower would build these units with limit switches on the winches that force 
a stop in the same place all the time.

###  The 'easy' method would be to hit the  'up'  switch..and run it to the top.
Then when it hits the upper limit switch, it stops.  Then manually  drop it say 1-2',
then stop it.   Same deal when lowering,  drop it fully nested... then raise it 1-2'.
If doing all this from inside the shack, the ust box  will tell you when it's fully extended or
nested. [leds]. Then just hit the down switch for maybe a few secs.  You could vary
the procedure a bit, and stop it somewhere between 89'..and say 86'.  And the same 
spread when nested.
