All High Performance Fibers (HPF) have their specific and unique features, which make them ‘High Performance’. On the other hand, every one of them has its specific disadvantages. Flip sides of the coin that make them great, but not perfect. Like Vectran®: high strength, excellent creep properties and a high temperature resistance. But at the same time a limited UV resistance. Or Dyneema®: strong, UV stable and chemically inert, but...only available in white. Too bad you can’t get any Dyneema® yarn in striking red or distinctive blue.
