A friend re-rigged their Niagara 35 with all dyneema (not sure of specific brand, but I think it was Colligo) about 10 years ago as part of a rig replacement when the boat fell over during a hurricane in Mexico. It's still going strong. They sailed for several seasons in Mexico, then 28 days non-stop from Mexico to BC via the clipper route during covid, and at least once around Vancouver Island since then, so not just coastal sailing. I will definitely be looking into this option when it comes time to re-rig, although we're currently boatless again...
