I use Torque Arms and a Star Guy assembly on my main tower.
Great engineering and has survived storms >85mph (the tower).
Have lost some antenna elements though (snapped off).

Torque Arms on secondary tower.

Cheers,
James

 Did a little more digging
 into hurricane Isabel.
 
 Gusts were measured in the Norfolk area up to
 74 mph, which compared
 to other hurricanes
 may seem tame. At landfall, Isabel was a category
 2, but was geographically very large, and at
 one point a category 5.
 K4JA's QTH was
 on the western side of Chesapeake Bay, with the
 hurricane's incoming winds direct over
 water for some 10 miles. This
 meant that
 incoming winds had little to no attenuation from ground
 clutter at K4JA QTH, probably for most of the
 wind directions
 experienced.
 
 It did cause a lot of damage
 in eastern North Carolina, Virginia and
 Maryland. Here's the damage and
 consequences enumeration just from the
 state
 of Virginia. Ref:
 http://www.vaemergency.gov/news-local/hurricane-history/
 
 Hurricane Isabel, Sept. 18,
 2003 (figures from Sept. 18, 2003 through
 April 30, 2004)
 
 Localities declared major disaster areas:
 100.
 Fatalities: 32.
 Total
 damages (not including economic losses): $1.9 billion.
 Homes destroyed: 1,124.
 Businesses destroyed: 77.
 Homes
 damaged: 9,027.
 Businesses damaged:
 1,400.
 Total amount of debris: 20 million
 cubic yards (equals 200,000 football fields).
 Dump trucks used to haul debris: more than
 660,000.
 Water delivered to localities 1.5
 million gallons.
 Meals served: 1.4
 million.
 Ice delivered to localities: 6
 million pounds.
 Generators provided to
 localities: 150.
 Calls received at the
 Virginia Public Inquiry Center: 6,000.
 People who registered with FEMA for assistance:
 93,000.
 
 Recovery
 Assistance
 
 Housing
 assistance (home repair, rental assistance): $33 million.
 Other Needs assistance (personal property,
 medical, transportation,
 miscellaneous): $22
 million.
 Small Business Administration
 loans: $79 million.
 Mitigation: $15
 million.
 
 Public Assistance
 (state agencies, local government, utilities)
 
 Debris removal: $179 million
 ($50 million of that for VDOT).
 Total for
 road systems, water control, public buildings/equipment,
 public utility systems, and parks and
 recreation: $36 million.
 For state agencies:
 $25 million.
 Federal Highway: $30

 In that
