Re: Spectre rope
Just to be clear,
Dyneema and Spectra are the same thing. Spectra is just a trade name for the same material.
However standing rigging is NOT made from dyneema/spectra. It should only be made from Dynex Dux which starts as a dyneema line, and is further treated to reduce stretch, increase strength, and decrease diameter. But at the cost of flexibility. Dux fresh off the spool is very stiff, and can stand proud like a measuring tape. It is not interchangeable with standard dyneema lines.
For a trailer sailor, or cruiser I would highly recommend it. The first time you install it you won't save any over wire, but from there on out you just replace the line every 8 years or so, the fittings can be reused.
