I believe you might be mistaken.  I have flown large, multi-line sport kites
for years and since Spectra lines became available, they have been the lines
of choice for serious kiters.  This is because of the characteristics of low
diameter to strength, very, low stretch and extremely slick surface.
Multi-lines made of Spectra can be twisted upon themselves many more times
than any other lines and still be easily controlled because they are so
slick.  These wrapped Spectra lines, on large kites, and with high winds,
are under extreme tension and certainly don't cut themselves.  Actually, if
crossed with other common kite lines made from Dacron or Kevlar, the Spectra
lines are easily cut by the other lines because of Spectra's very low
melting point.

Kevlar, on the other hand, is very abrasive.  Are you sure you are not
thinking about lines made from it?  Because of the properties already
mentioned, plus the fact that Spectra doesn't absorb water and is very
buoyant, I would think it would make an excellent tow line.
