Spyderline Dyneema SK-75

Made a startling discovery on Saturday.  The line we bought for the tramp is already rotting.  I admit, we tried to save a couple bucks, and it showed.  The line on a broken catamaran that has been sitting out unprotected for over five years is still fine and dandy.  I quickly did a half day's worth of research, found this Spyderline on a few websites and in the West Marine catalog.  Apparently, the secret is in the Dyneema's strength.  I chose the polyester wrapping of the Spyderline because the polyester is supposed to be highly abrasion resistant.  It ships Friday, so I will post pictures of it when it arrives.  It will be interesting to see how this lasts.
