I've just got a rope up 60 feet or so in a maple tree, and I'm ready to 
string an inverted L.

My question - I have several stainless steel pulleys with about a 1" 
sheave. If I insulate the pulley from the haul-up rope, is it a 
good/bad/indifferent idea to string the inverted L wire (14 copper, 
stranded) through the pulley rather than just using an insulator to make 
the bend.  It strikes me that having the bend move, however slightly, on 
the wire is likely to be less destructive than just having a sharp bend 
moving through an insulator end..
