      That gauge wire is a waste for shunt-feeding.  If flexible is what you 
want, you can use #14 insulated stranded wire from Home Despot.  Probably 
around $20 for a 500 foot spool by now, but plenty flexible.  

     You might have heard/read that thick shunt wires provide better 
match/greater bandwidth/increased stamina, etc.  Just hang two or more of the 
thinner wires off some kind of insulating support (PVC or wood come to mind) 
off the tower and tie the top and bottom ends together to form a shunt wire 
with a larger effective diameter.  

     OOT (one other thing):  Keep your shunt wire(s) an appreciable distance 
away from the tower face.  My wires (I use two in parallel) are two feet off 
the Trylon tower face; I've seen others as much as five feet away.  I'm sure 
modeling will tell you why this is preferred; I just followed others' examples.
