Default dipole antenna design question

Hi folks:

I've got a 110' 80 meter dipole that I've used for the past 4
years. I have the dipole strung about 30' in the air and connected
between two trees.

Because of where the trees are and the location of my house, I've
needed to use a pulley that's attached to my chimney to keep the
dipole closer to my house. The pulley is located near the center of
the antenna, and it creates about a 25 degree angle from the chimney
to the other tree.

Each year I have to repair the antenna wire right around where the
pulley is. I'm guessing because I use a cheap antenna wire
(purchased at Radio Shack ... about 14 gauge I believe), that's why my
antenna keeps breaking. I don't see how the pulley's creating that
much wear on the antenna, although I'm sure it's possible.

Would you guess that I'd have better luck if I was to purchase a
stronger antenna wire, such as a copper-clad steel wire I can get at
Universal Radio? http://www.universal-radio.com/catalog/cable/wire.html

Thanks for your suggestions.

Clark
