Your concerns are well placed with antennas made of fiberglass and
dacron/kevlar cords.
Instead of a hexbeam, I would recommend looking at the Innovantennas
XR5T:

or the JK Antennas Navassa 5:
<

Both have boom lengths of 12 feet or less, cover 20 - 10 meters and
have optional 6 meter add-ons. Either should significantly out
perform the hex beams and - since they are aluminum antennas that do
not use UV sensitive fiberglass, kevlar and dacron components - should
significantly outlast the hexbeam with significantly less maintenance.
