Barrie:
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.
