How long will the Dyneema last compared to the wires?
Wires last for as long as you avoid fraying and kinking them (they could be done after a few times out, or keep going for decades, just depends). Dyneema has something like a 3yr lifespan, but opinions vary wildly. That said, dyneema slung hexes are about a jillon times more useful than those on wire, because they can acctually cam. Avoid those on wires, the extra $20 you have to spend every three years to resling them is well worth it.
