Topband: Corner insulator of Inverted L

[Pete Smith N4ZR]

I'm in the process of putting my inverted L back up, and have a 
construction question - how do you position and attach the corner 
insulator?  My support for the vertical section is an old maple, plenty 
tall but only really reachable with a pull-up rope by firing a 
tennis-ball gun over it.  The first time I put this up, I used a pulley 
with a deep insulated sleeve and passed the inverted L wire through the 
pulley.  Neat, it seemed - the corner was automatically positioned to 
keep the vertical portion the right length.  Unfortunately, over a year 
or so, the antenna wire flexing over the  pulley caused it to break, so 
this time around I'd like to use a rope through the pulley and an 
insulator at the corner.  Question is how best to do it, to minimize 
strain on the antenna wire, making it more durable.
