My sailmaker said that, contrary to the Sailing World article,that by the time splices and fittings were included, Dynema was more expensive than steel cable. It also needed to be replaced every 3 years, because of UV degradation.
Horse-potatoes! More frequent replacement is an additional cost, but a monkey can splice single braid dyneema by the manufacturer's instruction. If you are wanting gates, yes it is a little more complicated but you get to re-use those every time. Without the gates, it's a splice on each end with a thimble and tension with a strong cut-away lashing. Bob's your uncle.
As rope goes, Dyneema is quite UV resistant so I suspect that it may have a lifespan of more than 3 years, especially down to the minimum breaking strength required for lifelines. The pull/pushpit is likely to break before 1/4" Dyneema.
