I use both the fiberglass and aluminum cammo support tubes extensively
and they work well, although the fiberglass does not tolerate UV
exposure over long periods of time. I have used both types for the
vertical section of an inverted-L at 40 feet (a wire parallel to the
fiberglass masts, obviously) and the only warning is that they both sag
significantly when the fully assembled 40-foot length is pushed up
without other support.
There are also nice guy rings available (both metal and fiberglass
types) that simply slip over the narrow diameter of the tubes where they
couple together. My 40-meter 4-square uses the aluminum tube at all four
corners with guy rings at 28-feet and they are absolutely stable. I
generally just tie the Dacron line directly through the holes in the guy
rings with no problems.
The aluminum tubes are available locally (in Reno) but a bit pricey at
about $7.50 each.
