Flag companies use a rope with a Kevlar core and a nylon out side. Seams to be the best.
Flag companies use a steel core rope as well with a nylon rope jacket but it rusts breaks apart and the nylon rope breaks apart with it. Nylon lasts a Long time but it stretches like a rubber band. Polypropylene even the black UV carbon type thats sun resistance has that 10 year life span sun just east it up. You can get a mixed Polypropylene nylon combination from Netting stores that sell commercial fishing net equipment, but even that the sun eats it up. -- Jim K9TF _________________ Topband Reflector Archives - http://www.contesting.com/_topband
