To slightly change the direction of this thread, previous posts have
mentioned the use of Dyneema and Spectra cable for winch launching.
Are there any statistics yet to indicate useful life of such cable,
particularly in dry dusty conditions ?

The stuff seems to be pretty immune to environmental conditions. It's
reported to be especially good for use on highly abrasive surfaces like
asphalt or concrete. The biggest hazards seem to be contact with hot winch
parts or sharp metal edges.

Several clubs in Germany are reporting 2000+ launches without a break. Most
people are now thinking that the higher cost of Spectra is offset by its
longer service life, 20% higher launches and the fact that it's much nicer
to work with than steel.
